The boss praised Rubio on Special Report last night:

KRISTOL: I think given that the mood it in 2010 will be pretty antiestablishment, anti-Washington, I think some of these challengers have a pretty good shot. I think Rubio has a real shot against Crist. I would prefer him personally. I think he could win a general election.
