Tough to pick a winner so far

From NBC's Chuck Todd
This appears to be a very polite but substantive debate so far. The health care discussion should make the wonk wing of the Democratic Party very happy. The most striking thing about this confrontation so far is the improvement in Obama as a debater. There was a time that the gap between Clinton and Obama at these debates was vast. Tonight, there's hardly a difference; Obama's benefitting big time from the no-time limit rule. Clinton, btw, is doing well herself; both are making a very professional and, frankly, nice impressions to what is likely to be one of the largest debate audiences to date.
