Advisers to the main Republican presidential contenders have told Politico that their next mission after the midterms is to stop Sarah Palin's quest for the White House.

In a Sunday interview with Fox News, Palin blasted Politico's reporting as "crap."

"Interviews with advisers to the main 2012 presidential contenders and with other veteran Republican operatives make clear they see themselves on a common, if uncoordinated, mission of halting the momentum and credibility Palin gained with conservative activists by plunging so aggressively into this year’s midterm campaigns," Politico's Mike Allen and Jim Vandehei wrote Sunday.

"There is a determined, focused establishment effort … to find a candidate we can coalesce around who can beat Sarah Palin," one anonymous top Republican told Politico.

Palin, seemingly cornered by the criticism, responded sharply.

"Politico, Mike Allen and Jim VandeHei, they're jokes," Palin said. "This is a joke to have unnamed sources tearing somebody apart limb by limb."

"If they would man up and if they would, you know, make these claims against me then I can debate them, I can talk about it, but to me they're making stuff up again," she told Fox News' Greta Van Susteren.

"And these are the brave people who want to lead the nation and run the world, huh? But they're not brave enough to put their name in an article," Palin continued.

"I don't think the paper that we just printed this article on, you know, it's not worth even wrapping my King Salmon in. I'll just ignore this crap," she said.

Palin's assault on Politico was her second jab at the media Sunday. Earlier on Fox News Sunday, Palin took aim at a CBS affiliate in Alaska that allegedly "conspired to make up stories about [Republican Senate candidate] Joe Miller."

Palin was referring to a message that was accidentally left on the voice mail of Joe Miller's spokesperson. The Miller camp claims that two CBS reporters were caught plotting to find and interview a child molester at one of Miller's rallies.

"That's sick. Those are corrupt bastards," Palin said.

On Fox News' America Live later Sunday, Dan Springer reported he could find no evidence to back up Palin's concern that KTVA is running a smear job against Miller.
