Bachmann insisted that people are taking a “second look” at the candidates’ stances.

“People are saying now that they don’t want to settle,” Bachmann said. “Because every four years, people are told that they need to go with the moderate in the race because that’s the only one who will win, now we’re seeing that’s not true that we can really have a true constitutional conservative for our nominee.”

Bachmann said her campaign is focusing on Iowa as the “number one” caucus. Recent polls have shown her support slipping.

Bachmann insisted that she was the Republican candidate who would go through with a “full-scale repeal” of the health plan passed by Pres. Barack Obama, which she called “Obamacare.”

“We have to go through this vetting process so the voters can take a good look at us and who they want to be their voice in the White House in 2012,” Bachmann said. “This is the key election, people need to know who will repeal Obamacare, who will repeal Dodd-Frank.”

Fox’s tight and symbiotic ties with the G.O.P. are well documented, but that does not rule out a Democratic detente, since it is still owned by Rupert Murdoch, a pragmatic mogul who has famously made peace with liberal politicians here and abroad.

Fox’s Republican role is out in force on Friday, however, as the RNC began an offensive against Obama based entirely on Bill O’Reilly’s framing from The Factor. A new RNC attack file contends Obama offered “conflicting threat assessments on Iran” based on “his interview with Bill O’Reilly.”

Some Democrats were also concerned about the Obama-O’Reilly exchange on Iraq. “Instead of presenting a clear definition of how he will realize the promise of change after eight failed years of George Bush, [Obama] blurred the distinction between himself and John McCain on Iraq,” lamented a former aide to Chris Dodd, who thrilled liberal Fox critics in a more combative exchange with O’Reilly during the Democratic primary last year.

“He gave up his greatest strength – opposition to the Iraq War – on O’Reilly’s show,” the operative continued. “If Obama’s lucky, he gained enough new Fox-watching supporters to make up for the Democrats he just alienated.”

The Obama campaign had no comment on the appearance or reaction from Democrats.

Robert Greenwald, the director of the documentary, “OutFoxed: Rupert Murdoch’s War on Journalism,” emailed a new video to supporters today. In it, he criticized Fox’s unbalanced treatment of Democratic politicians:

O’Reilly needled and interrupted Obama, trying to get him to simplify many of his answers — a far cry from the softballs O’Reilly lobbed at many prominent Republicans like Rudy Giuliani in the past.

In a separate interview with TWI, Greenwald said his new video shows how Fox News is using the same playbook this year that it effectively deployed against Sen. John Kerry’s presidential campaign in 2004.

“Those who don’t learn from history are forced to relive it,” Greenwald wrote in an email. “Here is proof positive of the Fox propaganda machine using the same language, the same tools the same attacks word for word against BO as they did against Kerry.” Raw Story, an alternative news site favored by the netroots, also criticized O’Reilly for a slanted, hectoring performance.
