McCain is much more Conservative than Warner is Liberal anyways.
Perhaps, but that's the point exactly -- there are plenty of Democrats who have switched against McCain because:
1. They want to dislike him because he is the GOP nominee; or,
2. He's the GOP nominee, and they don't want to like the GOP nominee, so they subconsciously search for reasons to dislike him.
There was actually an interesting study out on this last month. They did brainscans of political partisans and found that stories on neutral political topics went to the analytical center of the brain, while ones on partisan topics went to the emotive center.
It's not surprising (it's obvious and I'm dumb for posting about it
), but there's a whole lot of that around here.
