It's probably too early to tell if this is the start of a trend, but I offer it For What It's Worth:
Four votes for Fred Thompson from a family of evangelicals, which is interesting because, when I spoke to these same folks two weeks ago, none of them were Thompson supporters. In fact, they were barely aware of his candidacy. One was a Giuliani supporter and the others were looking fondly upon Huckabee, but hadn't made a decision.
Proving...? Nothing, of course. But this is a storyline I've been hearing from South Carolina all week: "Values voters" drifting away from Huckabee. This might explain why he decided to play the Robert E. Lee card in the final days of the campaign. Can't get the religion vote? Go for the rednecks.
