I've been looking at the crosstabs (premium access, I'm afraid) for yesterday's Rasmussen polls of five battleground states won by Bush in 2004 (VA, FL, OH, MO, and NC), and the news about religious blocs is this. Catholics in the South have shifted significantly toward Obama, most importantly in Florida, where Obama has turned what was a three-point deficit for Kerry into a 15-point advantage. And white evangelicals in Ohio, who backed Bush in 2004 by 75-25, now prefer McCain by only 65-33. If they had voted that way four years ago, Kerry would have carried Ohio by over 100,000 votes and been president for the past four years. Likewise with the Catholics in Florida, by a few hundred thousand votes.
