Ralph Hallow’s Washington Times article from yesterday talked about the possibility of a Newt Gingrich candidacy.  There was an interesting paragraph:

"If this election is about money and structure, then we already know who our nominee is," said Mr. Evans, alluding to the well-organized and financed Giuliani and Romney campaigns. "If it’s about ideas and a movement, then we may not know who our nominee is for a long time to come, because nobody has yet tapped into the core coalition of Americans who have a vision of where they think America should go."

Amen. I have not heard an answer to that at all. There are a variety of issues that are important, but no cogent worldview.
