Hosted by

In their second debate last night, ten candidates refined their arguments for the Republican presidential nomination. Will success in the primaries depend on the Christian right? What about moderates and independents in the general election? Does the GOP need a broader appeal than the one that elected George W.Bush? Also, Democrats in the Senate split over the Iraq War and, on Reporter's Notebook, what's the reason for rising food prices? Will there be any relief?
