Tim Pawlenty's the most important sleeper in the race. He has good ties to all segments of conservatives and in the Republican party. He's bright, he's articulate, he doesn't have foot-in-mouth disease; last night he handled the most difficult questions, and he did it well. Pawlenty, who does have presidential presence, will begin to rise.
