Contra Ezra, I think that if McCain chooses Joe Lieberman as his running mate it would be a disaster. McCain's entire strategy in the last few months, the strategy that has succeeded in moving the polls for him, has been predicated on attacking Obama's character and gathering in supporters on the right.
Why would he try and reclaim his maverick image, which wasn't getting him anywhere? Especially if Lieberman would undermine his standing with the conservative base -- Karl Rove knows whats up. A more prosaic reason, however, is that Lieberman actually hurts McCain's polling numbers in Florida, where he was expected to provide a boost among the state's substantial Jewish population.
