There are credible reports that delegates for McCain and Paul were instructed to switch their support to Huckabee in order to deny Romney a victory.
There are some things about Romney as a candidate that I don't like. Still, I have to wonder if a big part of the anti-Romney sentiment isn't thinly veiled religious bigotry.
I was watching both Bay and Pat Buchanan earlier, and both of them alluded to this issue. I think that they feel that the religious right abandoned them in 1992. I have to wonder if they feel that it was because they are Catholic.
