UPDATED WITH FINAL NUMBERS CBS News and Knowledge Networks conducted a nationally representative poll of approximately 500 uncommitted voters reacting to the debate in the minutes after it happened.
Thirty-nine percent of uncommitted voters who watched the debate tonight thought Barack Obama was the winner. Twenty-four percent thought John McCain won. Thirty-seven percent saw it as a draw.
Forty-six percent of uncommitted voters said their opinion of Obama got better tonight. Thirty-two percent said their opinion of McCain got better.
Sixty-six percent of uncommitted voters think Obama would make the right decisions about the economy. Forty-two percent think McCain would.
Forty-eight percent of these voters think Obama would make the right decisions about Iraq. Fifty-six percent think McCain would.
We will have a full report on the poll later on. Uncommitted voters are those who don't yet know who they will vote for, or who have chosen a candidate but may still change their minds.
The margin of sampling error could be plus or minus 4 percentage points for results based on the entire sample.
