Debate Reaction

In a severe case of bad timing -- just days before the Pennsylvania primary -- Sen. Barack Obama gave his worst performance in a debate so far last night. It's not that Sen. Hillary Clinton "won" the debate, but Obama clearly lost it.

Chuck Todd: "Overall, with the spotlight on him very bright, Obama didn't step up. He got rattled early on and never picked his game back up. Clinton wasn't very warm (outside of he first few minutes), but she didn't have the spotlight on her very bright. And as we've noted here quite a few times, whenever the spotlight is on one candidate, the other seems to benefit. Last night, the spotlight was on Obama, and for a short period of time, expect Clinton to benefit. But the question is whether she can sustain any benefit since as the negativity goes on, she pays a bigger price than Obama. Let's see what Pennsylvania decides in five days. A big Clinton victory and this debate will be seen as an important turning point. But a narrow victory (less than five points) and she could find herself facing more calls to get out."

Walter Shapiro: "This was not an evening that will shimmer in Obama's memory book."

Andrew Sullivan: "It was a lifeless, exhausted, drained and dreary Obama we saw tonight. I've seen it before when he is tired, but this was his worst performance yet on national television. He seemed crushed and unable to react. This is big-time politics and he's up against the Clinton wood-chipper. But there is no disguising the fact that he wilted, painfully."

Marc Ambinder: "Keeping the score card, there's no way Obama could have fared worse. Nearly 45 minutes of relentless political scrutiny from the ABC anchors and from Hillary Clinton, followed by an issues-and-answers session in which his anger carried over and sort of neutered him. But Hillary Clinton has a Reverse-Teflon problem: her negatives are up, and when she's perceived as the attacker, the attacks never seem to settle on Obama and always seem to boomerang back on her."

Josh Marshall: "I don't think this debate will have much effect on the direction of the race. In fact, I've learned from past... experience that the candidate who wins on points in a debate often doesn't come out with the best result."

Joe Klein: "My guess is that Obama, simply by pointing out the dopiness of the questions in the first half of the debate, probably emerged from this better than Clinton did."
