Is Michelle Malkin embarrassed by Fox News?

Why do “tea party” cheerleaders in the media, like Malkin and Glenn Reynolds, insist on playing dumb about Fox News' role in the “grassroots” movement? Are they ashamed that Murdoch's outlet has showered today's anti-Obama rallies with millions of dollars in free advertising/promotion? Are they embarrassed that the “tea parties” are now synonymous with Glenn Beck? Are they ashamed that Fox News has hijacked the events?

I honestly don't understand why Malkin and co. refuse to be upfront about the cable news channel's central involvement. Is Michelle Malkin embarrassed by Fox News?
