Actually, I have see signs of Crazy Palin making a come-back. Some commentators are starting to question whether she is really as bad as some media have made her out to be. After all, she's a self-made woman, governor of a state, almost Thatcheresc in strength of character, and she's so far survived the leap to national prominence and scrutiny. Still a redneck though.
I think if McCain & Palin made it to the White House, the world would be a far more 'interesting' place. Not only that, the shows like Jon Stewarts 'Daily Show', David Letterman, Jay Leno etc would be able to carry on their dialog uninterrupted. If Obama/Biden get in, what will happen to political comedy? I suspect The Governator will get a lot more attention.
