The midterms: Primary Day

"What anti-incumbent fever? The party favorites are set to rack up wins in three heated Senate contests today, even over a Sarah Palin-backed insurgent," the New York Daily News writes.

One of us previewed today's races in Alaska, Arizona, Florida, and Vermont here.

ALASKA: The Anchorage Daily News writes of today’s primary: “It is a race attracting national attention, with the California-based Tea Party Express saying it's spent over half a million dollars on ads for Miller. Murkowski, the eight-year incumbent, has also spent big, with the bulk of her campaign contributions coming from outside of the state.”

"Murkowski was leading" Palin-backed Joe Miller "by double digits going into Election Day. University of Virginia's Larry Sabato: "It says more about Sarah Palin. It tells you that even within the Republican Party in her home state, what her level of influence is."

ARIZONA: "John McCain appeared so confident of a Senate GOP primary victory over former Rep. J.D. Hayworth Monday that he used one of his final campaign stops to boost another congressional down-ballot candidate," Republican Iraq war veteran Jonathan Paton, who is running for the 8th Congressional District against Tea Party challenger Jesse Kell, Politico writes.

“The question now is whether Mr. McCain’s sharp shift to the right during the campaign -- the onetime maverick declared at one point that he no longer wanted anything to do with that label -- will ultimately come back to haunt him and perhaps tarnish his legacy as a pragmatist willing to reach across the aisle,” the New York Times adds.

ARKANSAS: Sen. John Thune will campaign for Rep. John Boozman today in his bid for the Senate, The Hill reported over the weekend.

FLORIDA: “Republican voters will decide Tuesday if they want a career public servant or a wealthy newcomer to get their party's nomination for Florida governor… [Attorney General Bill] McCollum was the party's presumptive nominee until [Rick] Scott jumped in the race suddenly in April.” Scott “moved to Florida seven years ago from Connecticut,” the AP writes.

“Facing only token opposition in her primary, Democrat Alex Sink is expected to emerge victorious Tuesday but with one big problem: In her quest to become governor, she is unknown to half of Florida's voters,” the Miami Herald notes.

IOWA: Why isn't Leonard Boswell seen as being in more trouble? "Iowa Republicans have sunk a lot of time and resources into defeating longtime Democratic Rep. Leonard Boswell, and with winds at the GOP’s back, this could be the year it pays off. But state Sen. Brad Zaun wasn’t Republicans’ top choice, and after having trouble harnessing national and state momentum in his district, he has suffered a few costly stumbles," Roll Call reports. "On Thursday the Des Moines Register reported that in 2001 while Zaun was mayor of Urbandale, a suburb of Des Moines, police had to ask him to leave an ex-girlfriend alone. The article alleged that Zaun, who was divorced then but is now married again, came to the woman’s home after midnight and pounded on her windows, calling her names. When he followed up with a phone call, a police officer answered and asked him not to contact her again."

NEVADA: Another ad from Sen. Harry Reid labels Republican opponent Sharron Angle as "just too extreme," this time on her support of eliminating the Department of Education.

OHIO: The New York Times notes how Democrats are trying to use George W. Bush against Rob Portman (R) in the state’s Senate contest. “‘Rob Portman is the No. 1 George Bush look-alike in the country,’ Senator Sherrod Brown, Democrat of Ohio and a Fisher supporter, said in an interview. ‘I just can’t believe the voters are going to choose the candidate who more than anybody else in the whole country represents what got us into this situation.’”

Portman’s response: “‘What the people in this plant want to know is what you are going to do for me going forward,’ Mr. Portman said. ‘That is all they care about, and frankly that’s what voters care about.’ ‘The world has moved on,’ he added. ‘Maybe the Democrats haven’t.’”

VERMONT: “Much of the focus over the last few months has been on the five Democrats running in their party’s primary for governor,” the Barre Montpelier Times Argus writes. “The winner of today’s race -- a hotly-contested battle that has already proven to be the most expensive primary in state history -- will face off against Republican Lt. Gov. Brian Dubie, who is unopposed among his party for governor.”
