These wingnuts are just getting warmed up. That was self-evident yesterday on Fox, when not just Glenn Beck, but Sean Hannity and Bill O'Reilly piled on as well. These guys are now headed straight for the rest of Obama's progressive appointees, and ultimately are after Obama himself.
Beck had on Michelle Malkin to help him line up the next row of victims, who appear primarily to be John Holdren and Valerie Jarrett. Hannity, too, clearly has Jarrett in his sights; he featured a clip from her chat at Netroots Nation, talking up the value of having someone like Van Jones in the administration.
But really, this bus isn't just aimed at progressive appointees. It's directed ultimately at Obama himself. Beck made that clear in his segment with O'Reilly (who miraculously comes off as the voice of reason in all this), when he essentially admitted that the purpose of this whole campaign is to paint Obama as a closet Marxist who secretly wants to transform America into a communist state.
In other words, this is about delegitimizing the Obama presidency. That's been their purpose from Day One, and they appear to be right on schedule. With a helping hand from the Obama White House itself.
