Over the last few years, McCain gave up nearly every substantive position that undergirded his maverick image. But he did retain the basic image that made him so popular among moderates -- the jocular yet dignified bipartisan figure who had a core sense of decency. (I acknowledged as much in a recent column.) Now, I think McCain is in danger of losing that as well, and that's why you see people like Weaver taking the extraordinary step of complaining in public.Chait has worn some of the biggest blinders when it comes to obscuring McCain 2008 with McCain 2000. If even he is starting to wake up then McCain is in real trouble.
