Chuck Todd suspects that they have completely different bases of support. Rudy is getting support from the Bush base, Todd argues, but he thinks most Giuliani supporters haven’t yet got a clue that Rudy is pro-choice, socially tolerant of gays, and in favor of some gun control. Rudy’s a Bush proxy – but a very fragile one. McCain’s supporters, on the other hand, know exactly what they think about him, and his current support is solid. That leaves a potential pool of Bush groupies up for grabs. McCain’s pandering to Bush makes even more sense now, doesn’t it?
