Tonight is not yet over, but I fear that one element in the voting may be a positive rejection of Romney. That seems to be a factor quite as much as an embrace of McCain. Hence the revival of Huckabee in the South. My southern belle wife always warned that many evangelicals would vote for anyone but a Mormon. I was skeptical — and we don’t yet have the exit poll breakdowns on that kind of question — but it looks as if something like that may be at work.
