It's interesting to see that while Christie does the best of all GOPers in Alaska, he does the absolute worst of all in Arkansas. And while Huckabee is much more popular than the other GOPers in Arkansas, he does in fact do the worst of all in Alaska (except Palin).
Christie does poorly in the South, but pretty well outside the South. That's a recurring trend in these polls. Which is why Christie as GOP nominee would yield the most interesting map.
Wait till voters learn that he is a corrupt bully. Then he won't be doing well anywhere.
