Althought somewhat dated, this article by Michael Barone is a nice analysis of the debate in South Carolina a couple of weeks ago between the 9 Democrats running for President.

Barone quickly dismisses Sharpton, Braun, and Kucinich and then focuses on three battles among the remaing six candidates: Dean versus Kerry on the Left, Gerphardt versus Edwards among the populists, and Lieberman versus Graham among the moderates.
