This Sunday saw the right-wing launch some nasty attacks on one of their own after Meghan McCain spoke out against Christine O'Donnell -- and was basically told by conservative pundits, “Sit down and shut up, woman.”

During her appearance on ABC's The Week on October 17, McCain said O'Donnell is “seen as a nutjob,” and explained, “I speak as a 26-year-old woman. And my problem is that, no matter what, Christine O'Donnell is making a mockery of running for public office. She has no real history, no real success in any kind of business. And what that sends to my generation is, one day, you can just wake up and run for Senate, no matter how [much] lack of experience you have.”

What did her political discourse earn her? Misogynistic attacks from right-wing pundits. Blogger Doug Powers kicked off the mud-slinging with a post on Michelle Malkin's blog Sunday morning. He began his post with a photo of McCain that spurred controversy after she posted it on Twitter a year ago and commented, “Disregard the above photo. I'm only putting it there to remind myself to check my tire pressure later this afternoon.”

Later that day, conservative blogger Dan Riehl on his blog Riehl World View referred to McCain as “Meggie 'Big Mac' McCain” and wrote that “this self-indulgent set of mega-breasts doesn't belong anywhere near a TV studio commenting on anything.”

Jeff Poor, a staff writer for the Media Research Center's Business & Media Institute, rounded out the evening by re-tweeting a conservative blogger's comment that “I swear, if Meghan McCain gets any dumber she'll be drooling on her boobs” with the remark: “Haha.”

Wow. All of these commentators would throw a fit -- rightly -- if sexist attacks were launched on Sarah Palin, Christine O'Donnell, or Sharron Angle. If they disagree with the substance of McCain's remarks, why are they going after her body instead?
