Per my sister, who had some run-ins with Huckabee supporters, most of those she met were elderly women or (politically misguided) committed Christians. I don't think Huckabee will take even a majority of the evangelical vote, but do think he will take enough away from Palin to give Romney several primary victories.
Methinks Bain Capital has been doing money transfers to Huckabee's account in the Turks and Caicos.
