The January 10 Republican Debate

Confident and near-cocky for the second straight debate. Easily deflected Romney and Giuliani attempts to take him down a notch. Got to talk about spending and defense for much of the night (his strengths) and even did just fine on the economy (an acknowledged weakness). Also managed the immigration issue without too much wobbling. His tone and demeanor reflected the view of his staff: unless someone stops him pronto, he will be the 2008 nominee of the Republican Party. And no one stopped him in this debate.
