Mainliners and Catholics on the Move?

White mainline Protestants and white Catholics both turned out for George Bush in 2004. In 2008, they may be on the move. So says John Green, every reporter's favorite source for religion and politics, who says mainliners and Catholics are "groups in motion" and could be lured to the Democrats if the right pitch is made.

From the Pew Forum's recent media summit in balmy Key West:

Now I don't know if these numbers will hold up next year. You could find other trial heats that would show slight differences. But they do suggest less-observant Catholics are one of those groups in motion. They move around, depending on who the candidates are and presumably what the campaign is about.
