Michele Bachmann, Jon Huntsman, and Rick Perry all took shots at Herman Cain for the latest allegations of an affair. Huntsman told the Boston Globe, “You’ve got to be reconsidering just based on how we have lost focus on the issues that really do matter. Every time another accusation comes up, it diminishes our ability to stay focused on the issues that really do matter for the American people. And I think that’s a disservice to the voters.”

Bachmann said on a Minnesota talk-radio show: "When [the latest accusation] came out yesterday, everyone said 'this is it he's done. People just don't see that there is an ability for him to be able to come back after that."

A Bachmann campaign aide yesterday Tweeted that moving trucks could be seen outside Cain’s Iowa headquarters, which is across the street from Bachmann’s. But they weren’t moving trucks, just a truck delivering signs, NBC’s Alex Moe and Jamie Novogrod report. The aide, state Sen. Kent Sorenson, who is heading up Bachmann’s campaign in Iowa, later said it was an “accident” and deleted the Tweet. But he added in a phone conversation with NBC’s Novogrod, “I think it's going to happen sooner rather than later."

Perry said this morning on Fox, per NBC’s Carrie Dann, that Cain’s "got to address these issues. Straight up." "If these allegations are true he has an obligation to his family and to the American people to explain."

BACHMANN: She also went after Gingrich in the radio interview: "I think all of these [frontrunner falls] do benefit me. I think that Rick Perry's slide in the polls benefits me, I think that with Herman Cain, and I think now we're re-looking at Newt Gingrich because more information is coming out."

Glenn Beck says he’s voting for Bachmann, something she touted in an email. “I am the candidate Glenn Beck trusts to lead America back to prosperity,” she said. She also got the endorsements of the co-chairs of the South Carolina Tea Party.

CAIN: The New York Post on Cain’s “reassessment” of his campaign: “The pizza king might not deliver to the White House.”

GINGRICH: Gingrich took a jab at Romney, calling him “the former frontrunner.”

Rep. Brian Bilbray, the GOP chair of the Immigration Reform Caucus, took a shot at Gingrich’s stance on immigration yesterday on CNN: “Newt, I don’t care who you are. Quit sending the mixed message that we are going to somehow reward or accommodate you if you broke the law while there are those waiting patiently and playing by the rules, waiting to come into this country legally.”

And Gingrich expressed support for the individual mandate on health care as recently as 2005.

HUNTSMAN: “Republican Jon Huntsman [yesterday] refused to rule out running as an independent candidate for president should he fail in his quest for his party’s 2012 nomination. Asked, ‘Is there any situation in which you would run for president as an independent?’ Huntsman told the Boston Globe, ‘I don’t think so.’ Told that anything but a flat denial could perpetuate speculation about the possibility, Huntsman replied: ‘I’m a lifelong Republican. I’m running as a Republican, and I fully anticipate that that’s where we’re going to be.’”

PERRY: The New York Daily News yesterday on Perry’s flubs about the voting age and the date of next year’s election: “Texas Gov. Rick Perry had another "oops" moment Tuesday….”

Perry had yet another “oops” moment on FOX this morning, one to which New Hampshire voters don’t take kindly. He noted how he's pushing his message "as we get ready for those New Hampshire caucuses." New Hampshire holds a primary, not caucuses, and touts it first-in-the-nation primary status.

ROMNEY: Taegan Goddard notes of his interview with Bret Baier on FOX last night, “Mitt Romney showed why he doesn't do too many interviews.” The Miami Herald, which Political Wire links to, called Romney “icily peevish” at times. “He laughed mirthlessly, or denied video evidence showed him shifting his positions or suggested he was espousing clear positions -- which nevertheless required clarification. When pushed, he told Baier at one point that people should read his book.”

In the interview, Romney said of his support for Massachusetts’ health-care plan, “If it keeps me from winning a primary, so be it.” Romney also took this shot at Gingrich: “He spent his last 30 or 40 years in Washington. I spent my career in the private sector.” He also called him a “lifelong politician.”

Just how unsatisfied are some conservatives with the field? A pro-Palin group is running a one-minute ad in Iowa (with a very small $6,500 ad buy) urging her to reconsider.
