The CNBC debate scheduled for tomorrow now features John Harwood as a panelist questioner, as well as Maria Bartiromo, in addition to Chris Matthews as moderator. Some Republicans had wondered whether a man who goes on and on about the criminality of Bush and Cheney can be expected to be a fair questioner for a Republican debate.

UPDATE: And Larry Kudlow is hosting the post-debate show, and promises to “rap” Matthews “very, very hard” if he gets out of line.
