An interesting formulation from Mike Huckabee's potential adviser as the Republican nominee, Dick Morris:
"He puts all of the Bible into play. It's not just 'thou shalt not, thou shalt not, thou shalt not,' but it's the positive aspects of his religion, too -- which is 'love thy neighbor,' and 'when I was naked you clothed me,' and a sense of helping poor people."
Or a spend-like-Jesus Republican. My take on Huckabee in the Sunday Times here.
