Good updates on what's happening in Iowa today with the Republican candidates here.
Prediction: I have the feeling that Huckabee's going to win Iowa. It certainly appears to be a race between Huck and Romney. Polls show it to be close. But I don't have the feel of a real Romney surge there; as Jonathan Martin reports in the link above, anecdotal evidence suggests that too many see Romney as phony, as not real. That will allow Huckabee to hold on.
That doesn't necessarily make Huck the national front-runner. There are a lot of primaries to come, and I don't see New Hampshirites or Floridians or South Carolinians meekly ratifying Iowa's choice. This is merely the end of the beginning for Republicans.
The most important thing for GOPers and for conservatives is to continue to force these candidates to flesh out their conservative principles and positions. We're not nearly done with that process yet.
