FITZWILLIAM, N.H. -- The national debate over gun laws traveled to another New England town on Thursday, as Sen. Kelly Ayotte, R-N.H., told constituents that universal background checks could lead to a "registry" of gun owners.

"In terms of a universal background check, as it's been framed, I have a lot of concerns of that leading to a registry that will create a privacy situation for lawful firearms owners," Ayotte said. 

The remarks came during a town hall here in southern New Hampshire, after a man asked, "What's wrong with universal background checks?"

The back-and-forth was another sign that Ayotte's vote against a gun bill last month continues to trail her.   The bi-partisan bill, negotiated by Sens. Joe Manchin, D-W.Va., and Pat Toomey, R-Pa., would have enforced background checks for all gun buyers. 

Ayotte's vote against the legislation has not only made her a target for gun control advocates nationwide, but also has left her fielding questions and complaints about her stance on the divisive topic of guns from voters across her state. 

During a town hall Tuesday in Warren, N.H., Ayotte was confronted by the daughter of Dawn Hochsprung, the principal of Sandy Hook Elementary, who was killed by Adam Lanza in the Dec. 14 massacre in Newton, Conn.  Later Tuesday, in Tilton, N.H., members of the audience waved signs that read, "Demand action to end gun violence." 

Ayotte's comments echoed those of the National Rifle Association.  Appearing on NBC's "Meet the Press" in March, NRA executive vice president and CEO Wayne LaPierre dismissed the idea of universal background checks and invoked the threat of a national gun owner's registry.

"Here's the loophole: society, the H.I.P.A.A. laws, the mental health laws, the medical records," LaPierre said. "The Adam Lanzas, the shooters in Aurora, the shooters in Newtown, they're unrecognizable. They're not going to be in the system. Who is going to be in the system? You and me.  And our names are going to be in the system. There is going to be a list created; that list will be abused. Some newspaper will print it all. Somebody will hack it. There will be a registry," LaPierre continued.

Although another Newton relative was in the audience here on Thursday, he did not ask a question. 

Gilles Rousseau, the father of slain teacher Lauren Rousseau, later told reporters he was there to push for background checks, but did not have an opportunity speak personally with the senator. 

"I want her to reconsider a vote.  This is not [a] national registry," Rousseau said.

Ayotte told the crowd that she is in favor of strengthening prosecutions of gun crime and making improvements to mental health care.  

Updated 5:20 p.m. - Senate Republicans managed to achieve their goal of blocking U.N. Ambassador Susan Rice from becoming the next secretary of state after Rice, on Thursday, withdrew her name from consideration by President Barack Obama.

Republicans were more measured in their responses to the withdrawal than they had been in their earlier criticism of Rice, whose prospective nomination had come under fire for her role in publicly explaining the Obama administration’s assessment of the Sept. 11, 2012 attacks on a U.S. consulate in Benghazi, Libya.

"I respect Ambassador Rice’s decision. President Obama has many talented people to choose from to serve as our next Secretary of State," South Carolina Sen. Lindsey Graham said in a statement.

Graham, along with Sens. John McCain, Ariz., and Kelly Ayotte, N.H., had led an effort to pre-empt Obama from naming Rice as the successor to outgoing Secretary of State Hillary Clinton.

"I respect Susan Rice's decision and appreciate her commitment to public service," Ayotte said in a statement. "However, my concerns regarding the terrorist attack in Benghazi go beyond any one individual."

Rice told NBC News in an exclusive interview on Thursday that she no longer wished for Obama to consider her for the position. In a letter to the president, Rice said she feared a confirmation fight in the Senate "would be lengthy, disruptive and costly."  The full interview with Rice will air tonight on Rock Center with Brian Williams at 10 p.m ET.

McCain’s office said: “Senator McCain thanks Ambassador Rice for her service to the country and wishes her well.”

Each of the Republicans, though, expressed continued concern about the Benghazi incident in their statements, and said they would continue their efforts to probe the matter.

Obama said he has accepted Rice's decision, hailing her as an "extraordinarily capable, patriotic, and passionate public servant." He said Rice would continue to serve as U.N. ambassador, and as a member of his national security team.

The trio of Senate Republicans had vowed to work to block Rice's nomination if Obama settled upon the United Nations ambassador as his nominee, stemming from her explanation for the Benghazi attacks. Rice had appeared on public affairs shows the weekend after the attack to assert that the assault -- which left four Americans dead, including Amb. Christopher Stevens – to assert that it was the outgrowth of a spontaneous rally to protest an American video that was offensive to Islam.

An investigation in subsequent weeks revealed that the attack in Benghazi was actually a coordinated terrorist attack, which prompted pointed questions from Republicans about why the administration had first put Rice forth to assert otherwise. Republican presidential nominee Mitt Romney tried for a series of weeks to effectively tarnish Obama politically with the mixed public explanation.

McCain, Ayotte and Graham pressed the matter further after the election, winning a meeting with Rice last month amid speculation that Obama wished to name the trusted adviser to fill the top diplomatic job.

"If Sen. McCain and Sen. Graham and others want to go after somebody, they should go after me," Obama said at a press conference following his re-election to rebuff the Republican troika. "And I'm happy to have that discussion with them. But for them to go after the U.N. ambassador who had nothing to do with Benghazi, and was simply making a presentation based on intelligence that she had received, and besmirch her reputation is outrageous."

But there were indications that the critiques had started to wear on the public perceptions of Rice. In the NBC/WSJ poll released Wednesday, Rice was rated positively by 20 percent of respondents, while 24 percent of said they had a negative perception of her.

TAMPA, Fla. -- South Carolina Sen. Lindsey Graham (R) called on government contractors to put employees on layoff notice before November's election as a way to pressure Congress to address the so-called "fiscal cliff."

Graham, joined by Republican Sens. John McCain (AZ) and Kelly Ayotte (NH), were in Florida for their first stop on a  two-day, four-state tour by these three members of the Senate Armed Services Committee designed to bring attention to the $500 billion in automatic cuts scheduled to begin in January if Congress does not find other ways to cut spending.

“Politicians, you know, quite frankly respond to pressure,” Graham said about the  cuts set to begin in 2013 under the so-called sequestration budget.

“I’m urging every defense industry that could be affected by sequestration to put your employees on notice before November,” he continued. “The more it becomes real to us as to what comes the nation’s way, the more likely we are to solve the problem.”

Graham delivered the remarks inside a University of South Florida auditorium here in Tampa this morning to an audience of military veterans, academics, and defense contractors.

Some in the audience were linked to nearby MacDill Air Force base, a sprawling installation housing the U.S. Central Command, the organization that oversees America’s military activity in the Middle East, including Iraq and Afghanistan.

“There is gridlock in Washington,” McCain said as he warmed the crowd shortly after taking the podium. “I don’t need to tell you that.  It’s hard these days, trying to do the Lord’s work in the city of Satan.”

The line won laughs, but much of the humor today was strictly of the gallows variety.

Before the event began, audience members mingled and expressed satisfaction that South Florida’s defense industry was being recognized.

“I think they’re playing politics with peoples’ lives,” Donna S. Huneycutt, the executive vice president of a small government consulting firm, said of Congress in an interview. 

Huneycutt said she has a staff of 62 people, and nearly had to lay people off last year as a result of earlier budget cuts.

“I’d like to see both sides come to the table and compromise,” she said.

McCain, Graham, and Ayotte called for a bipartisan solution to the crisis.

They signaled they would break with other Republicans and would accept closing loopholes in the tax code in return for concessions from Democrats, including cuts to entitlement programs.

“We shouldn’t put our troops in this position,” Ayotte said. “We shouldn’t put our military feeling like they have the sword of Damocles hanging over their head.”

Ayotte, the wife of a retired Air National Guard pilot who flew combat missions over Iraq, is a buzzed-about prospect for the number-two slot on presumptive Republican presidential nominee Mitt Romney’s ticket and is rumored to be on his short list.

The town hall tour was scheduled to make stops later today in Fayetteville, NC and Norfolk, VA – also home to key military communities.

The tour will wrap Tuesday morning in Merrimack, NH at a facility for the defense contractor BAE Systems.

As Mitt Romney approaches his announcement of a running mate, a series of clues about whom he might pick continue to seep into the media.

The presumptive Republican presidential nominee's campaign confirmed, per NBC's Garrett Haake, that New Hampshire Sen. Kelly Ayotte (R) would meet with Romney and march with him at a Fourth of July parade tomorrow in Wolfeboro, N.H.

New Hampshire Sen. Kelly Ayotte plans to meet with presumptive GOP nominee Romney and march with him at a Fourth of July parade in Wolfeboro, N.H.

Ayotte is one of several rumored short-listers who have appeared with Romney on the campaign trail; these ventures have been interpreted as informal tryouts for potential GOP tickets. A slew of other vice presidential hopefuls joined Romney on his bus tour through the Midwest last month.

Meanwhile, this morning on CNBC, New Jersey Gov. Chris Christie seemed to warm to the idea of serving as Romney's pick for a vice president.

"I love being governor of New Jersey, you can tell," Christie said. "But the fact is, if Gov. Romney picks up the phone and calls, you have to answer the call and listen at least."

Romney himself has said little about the vetting process since being forced to acknowledge in June that his campaign was evaluating Florida Sen. Marco Rubio, among other candidates, for the VP nod.

The list of other top-tier candidates is considered to include Ohio Sen. Rob Portman (R) and former Minnesota Gov. Tim Pawlenty (R).

Another governor long rumored to be among favorites for the vice presidential nod is Bob McDonnell of Virginia. It might be difficult for him to serve as Romney's running mate, though, in his new role, announced Monday, as chairman of the platform committee at this summer's Republican National Convention.

ARLINGTON, VA -– Mitt Romney deployed New Hampshire Sen. Kelly Ayotte to speak on his behalf at a pro-life conference just outside the nation’s capital Friday morning, where she repeatedly attacked President Barack Obama.

“How we treat the weakest among us is truly a reflection on who we are as a nation and President Obama’s record shocks the conscious when it comes to protecting life and unfortunately on many other issues as well,” Ayotte told the crowd at the National Right to Life conference. “He has a vision of America that is very different from what we want for our children and our grandchildren. I shudder to think what would happen in a second term.”

Sen. Ayotte, who is commonly mentioned as a possible vice presidential choice for Romney, talked highly of the man she endorsed early on for president this cycle.

“I want you to know, that Gov. Romney is a fighter who will stand up for life and he will restore conservative values based on our moral, our moral grounding in the White House and he will govern as a pro-life president,” she said inside a Hyatt hotel ballroom here.

Referring to the presumptive GOP nominee as “my friend” and “a strong leader” during her roughly 20 minute address, Ayotte laid out just how important she believes the election on November 6 is for the country.

“Life is on the line in this election –- it truly is and we can’t afford to just play defense, we have to get on the offense and we need to elect a pro-life president. We need to elect Mitt Romney to make sure we protect life in the White House,” she said and even jabbed Obama for always having so many celebrities campaigning with him.

“When you stand up for what is morally right, when you stand up for those who don’t have a voice –- that is much more powerful than any celebrity that can come in this room.”

Ayotte, the former Attorney General from New Hampshire, told the several hundred people in attendance that she is the only female pro-life senator in Congress and would work as hard as she could to fight for the future of this country.

The event Friday morning was originally planned as a prayer breakfast but organizers changed it Thursday afternoon to a rally aimed at repealing Obamacare after the Supreme Court’s ruling to uphold President Obama’s healthcare law.

“Yesterday’s Supreme Court decision highlights what is at stake in this race,” Ayotte noted during her address.

Kansas Gov. Sam Brownback, who once backed Texas Gov. Rick Perry in the GOP primary, keynotes the closing banquet of the three-day conference Saturday evening. In addition to sending Ayotte on his behalf, Gov. Romney also sent a video message to attendees.

Updated 1:00 p.m. - Among the flurry of conservatives vowing to redouble their efforts to repeal President Obama’s health reform law was the handful of Republicans whom Mitt Romney might pick as a running mate.

Below is a rundown of portions of their statements, which we will continue to update throughout the day.

Ohio Sen. Rob Portman:

While the Court has deemed the law constitutional as a tax on the American people, it is still flawed policy that is unaffordable for our families, our small businesses, and our government.  The President's one-size-fits-all health care spending law is the centerpiece of a failed agenda that has increased economic uncertainty, stalled job creation, and deepened the spending hole that Washington has dug. 

Florida Sen. Marco Rubio:

What's important to remember is that what the Court rules on is whether something is constitutional or not, not whether it's a good idea. And while the Court has said that the law is constitutional, it remains a bad idea for our economy, and I hope that in the fall we will have a majority here that will not just repeal this law, but replace it with real solutions that will insure more people and cost a lot less money.

Wisconsin Rep. Paul Ryan

Today’s decision strengthens the case for repeal and replace. With the right leadership in place, I am confident we can advance real health care solutions for the American people. It is now in the hands of the American people to determine whether this disastrous law will stand.

Virginia Gov. Bob McDonnell:

Today's ruling crystallizes all that's at stake in November's election.  The only way to stop Barack Obama's budget-busting health care takeover is by electing a new president. Barack Obama's health care takeover encapsulates his Presidency: Obamacare increases taxes, grows the size of government and puts bureaucrats over patients while doing nothing to improve the economy.

New Jersey Gov. Chris Christie:

Today's Supreme Court decision is disappointing and I still believe this is the wrong approach for the people of New Jersey who should be able to make their own judgments about health care. Most importantly, the Supreme Court is confirming what we knew all along about this law - it is a tax on middle class Americans.

New Hampshire Sen. Kelly Ayotte:

By imposing a coercive tax on the American people, the president's health care law represents an unprecedented federal overreach into individuals' personal lives. ... If we don't repeal it, Americans can expect to see higher costs, less choice and fewer jobs.  I will continue to fight to repeal this law and replace it with market-based reforms that reduce costs and expand consumer choice.

Louisiana Gov. Bobby Jindal:

Ironically, the Supreme Court has decided to be far more honest about Obamacare than Obama was.  They rightly have called it a tax. Today's decision is a blow to our freedoms. The Court should have protected our constitutional freedoms, but remember, it was the President that forced this law on us.

Mitt Romney’s search for a running mate appears to have narrowed, as clues to whom Romney might select as his No. 2 begin to pile up in the media.

A campaign that prides itself on discipline had, to date, exacted tight control over the process of vetting candidates to serve at the former Massachusetts governor’s No. 2, a fact that Romney bragged on Tuesday.

"I get a kick out of some of the speculation that goes on," Romney told Sean Hannity of Fox News in an interview to air this evening. "I'm not going to comment on the process of course, but I can tell you this: only Beth Myers and I know who is being vetted."

That comment came amid new reports on Tuesday that Marco Rubio, the popular Florida Republican senator, had not been asked – yet, at least – to submit the materials typically associated with vetting a vice presidential candidate.

ABC News initially reported that Rubio wasn’t being vetted, and the Washington Post followed up with indications that Rubio hadn’t made it past an initial review by Romney’s high command.

Romney’s quip to Fox served as a knowing acknowledgement, though, of what members of the media have encountered in their search for details on the veepstakes: News is fleeting, largely because the Romney campaign’s high command keeps details on lockdown.

Even some of the most plugged in advisers to Romneyworld profess genuine ignorance of the vetting process.

Myers, Romney’s former chief of staff as governor, is leading the search for a prospective vice president. She might lack some of the skills of political figures previously tasked with her job – John McCain had power lawyer A.B. Culvahouse lead his vetting in 2008 – but Myers is described as a figure whom Romney holds in high esteem. She was selected precisely because it would mean no leaks, and because she understands Romney and his desire for an experienced vice presidential candidate who won’t overshadow the top of the ticket.

Other broad contours of the process have emerged, too. A New York Times story earlier this week floated the idea that Romney could introduce his choice in July, well before the Republican convention in August. Most presidential nominees traditionally reveal their choice of a running mate shortly before their nominating convention.

GOP candidate Mitt Romney speaks at a campaign event at the Bavarian Inn Lodge in Frankenmuth, Mich.

The Times also included a kicker paragraph that suggested that the Romney campaign might be wary of selecting Chris Christie, since the bombastic New Jersey governor might threaten to overshadow Romney.

One informal Romney adviser suggested that a candidate who’s seen his stock improve is former Minnesota Gov. Tim Pawlenty, in part because Pawlenty would do anything but overshadow Romney. A runner-up in the 2008 veepstakes, Pawlenty is said to be especially appealing to Ann Romney, who’s built a rapport with Pawlenty’s wife, Mary.

Ohio Sen. Rob Portman and Wisconsin Rep. Paul Ryan are also generally perceived as short-listers for Romney. Each of them, along with Pawlenty, joined Romney for portions of his swing-state bus tour over the last five days.

Officially, most of the Republicans thought to be candidates for the vice presidency have also declined to comment on the process.

"I won't discuss the vice presidential process, out of respect for Gov. Romney," Rubio said Tuesday on CNBC. "I know he is going to make a great choice."

That means that, until the pick is made known, observers are more likely to learn about the process through candidate attrition. Case in point: Indiana Gov. Mitch Daniels agreed to become the next president of Purdue University, removing his name from the list of candidates, though he wasn’t ever seen as Romney’s likely running mate.

The few-and-far-between details stand in contrast to the McCain campaign in 2008, which had basically broadcast publicly that the Arizona Republican wished to select his friend, the independent Democratic Sen. Joe Lieberman of Connecticut, as his running mate. With the exception of McCain’s ultimate selection of Sarah Palin as his vice presidential nominee, much about the Republican’s campaign wasn’t secret.

The Romney campaign seems determined to learn from McCain’s mistakes, maybe even to a fault. The process of vetting a vice presidential candidate can be political in its own right; look no further than a top Rubio advocate’s pushback to BuzzFeed about the Florida senator’s supposed exclusion from Romney’s short list.

But in leaking few details about their search, the Romney campaign also loses out on an opportunity to show they’ve at least made an effort to seek out various candidates whose mere consideration might be needed to placate certain corners of the party.

In particular, few women except for New Hampshire Sen. Kelly Ayotte – a freshman lawmaker from New England with only scant federal experience – are thought to be under consideration by Romney.

"I think, unfortunately, Palin poisoned the well on that," said one informal Romney adviser, fretting that any woman selected as VP would draw inevitable comparisons to the former Alaska governor. "I would guess if I were inside the Romney mind that they're worried that any woman chosen will be subjected to a higher level of scrutiny. "

But beyond Rubio, there are virtually no candidates for the vice presidential slot who would represent any diversity on the Republican ticket, a dicey proposition given Romney’s political deficits with women and Latino voters, as well as his opponent this fall: the nation’s first black president.

PORTSMOUTH, NH -- Mitt Romney's short list of vice presidential candidates is expected to include 10 to 15 names, a source with knowledge of the deliberations said Monday as one of those potential candidates, Sen. Kelly Ayotte, joined Romney on the campaign trail this morning.

Making his first appearance in the Granite States since having assumed the role of the presumptive Republican nominee, Romney was flanked by Ayotte, a longtime ally who's now receiving new scrutiny as a possible contender for the No. 2 spot on the GOP ticket this fall.

A freshman senator and former New Hampshire attorney general, Ayotte, who endorsed Romney last November, toured the port here with Romney this morning, and introduced him, telling a crowd of supporters and local fisherman "help is on the way" under a Romney presidency.

The stop was sure to stoke speculation due to its spot in a series of campaign stops Romney has made with potential candidates to round out his ticket. He campaigned heavily in Wisconsin with Rep. Paul Ryan, and Florida Sen. Marco Rubio, another vice presidential favorite, appeared with Romney last week in Pennsylvania.

"There's a whole ledger of items you check off, and Senator Ayotte is a strong candidate on the list," Former New Hampshire Governor and White House Chief of Staff John Sununu told reporters. "She knows how to cut budgets. She knows that you cut spending instead of raising taxes to cut budgets. She's a hard campaigner. She's earned the respect of her colleagues on both sides of the aisle in Washington."

Sununu, whom Romney described in his remarks as a "bulldog" for the campaign, played down the notion that today's appearance in Portsmouth constituted an audition for Ayotte. He pointed to her previous appearances and work for Romney, and the former New Hampshire governor suggested that Romney would continue to appear with GOP heavyweights in swing states.

But Sununu also raised eyebrows when he suggested that the vice presidential search committee, being led by longtime Romney aide Beth Myers, would be working with an extensive short list of prospective running mates.

"I know that the bowl has about 19 or 20 little folded pieces of paper in it, and they keep shaking the bowl," Sununu said.

A source with knowledge of the deliberations thus far called that number "a little high" and said the working list contained somewhere around ten to fifteen names instead.

Ayotte might earn her way onto that list because of her experience in law enforcement and background in the swing state of New Hampshire. Adding a woman to the ticket might help Romney to close the gap with women voters, as well.

But, even as Sununu acknowledged, Ayotte has little relative experience on the national stage -- something that could open her up to attacks on her inexperience.

But for all the speculation surrounding the second spot on the GOP ticket, the man at the top remained almost exclusively focused on the economy in his remarks today, accused the president and his campaign of engaging in "silliness" and distractions, and saying he would remain focused on "helping those that need help the most."

"I wish the president would start talking about the economy and stop trying to divert with all the silliness day in and day out," Romney said. "Let’s focus on what people care about, and the issue people care about is the one that is effecting us, which is their pocketbooks. The gasoline prices. The cost of higher education. The need for more jobs. The need for better incomes."
