Follow-up numbers are coming in now:

A national poll of people who watched the first presidential debate suggests that Barack Obama came out on top… Fifty-one percent of those polled thought Obama did the better job in Friday night’s debate, while 38 percent said John McCain did better.

Men were nearly evenly split between the two candidates, with 46 percent giving the win to McCain and 43 percent to Obama. But women voters tended to give Obama higher marks, with 59 percent calling him the night’s winner, while just 31 percent said McCain won.

(CBS) The first presidential debate helped uncommitted voters learn about the candidates - and it appears that Democrat Barack Obama benefited the most, according to a CBS News/Knowledge Networks poll taken immediately following the debate.

Uncommitted voters said Obama won the debate against Republican John McCain, and more of those voters improved their opinion of the Democrat. But while 66 percent think Obama would make the right decisions about the economy, 56 percent think McCain would do so about Iraq.

Immediately after the debate, CBS News interviewed a nationally representative sample of nearly 500 debate watchers assembled by Knowledge Networks who were “uncommitted voters” - voters who are either undecided about who to vote for or who say they could still change their minds. Thirty-nine percent of these uncommitted debate watchers said Obama won the debate. Twenty-four percent said McCain won, and another 37 percent thought it was a tie.

Nearly half of those uncommitted voters who watched the debate said that their image of Obama changed for the better as a result. Just eight percent say their opinion of Obama got worse, and 46 percent reported no change in their opinions.

McCain saw less improvement in his image. Thirty-two percent have improved their image of McCain as a result of the debate, but 21 percent said their views of him are now worse than before.

Why did voters’ image of Obama improve? Many volunteered that they were impressed by his poise and knowledge about the issues, that he was more knowledgeable about the issues than they thought previously. When it came to McCain, those same voters said he “didn’t control himself well under pressure,” that he was “angry and bad-tempered,” and that he “talked too much about the past.”
