Lord help me, I’m defending Palin

What’s happening is that Palin has come to represent unhinged grassroots conservatism, and people in the media immediately (and incorrectly) associated Loughner with the far right. Moreover, the Republican establishment understands her potential candidacy as a liability and is looking to snuff it out. So you have this weird moment where Palin is on trial for something she has no connection with at all.
