CBS News, CNN, Public Policy Polling and Google Consumer Surveys online poll all registered wins for Obama after Monday's debate on foreign policy at Lynn University, a review of post-debate polling by The New York Times indicated.
The CBS News poll of undecided voters who watched the debate indicated 53 percent said Obama came out on top, 23 percent gave it to Republican challenger Mitt Romney and 24 percent declared it a tie. The margin of error was 4 percentage points.
A Public Policy Polling survey of voters in 11 swing states who watched the debate indicated Obama won, 53 percent to 42 percent. The margin of error was 4.4 percent.
A CNN poll of registered voters who watched the debate put Obama ahead, 48 percent to 40 percent for Romney, but the results were much closer after factoring in the 4.5 percentage point margin of error.
An online poll by Google Consumer Surveys indicated participants said Obama won, 45.1 percent to 35.3 percent.
Averaging results from the CBS News, CNN and Google polls, all of which surveyed viewers after all three presidential debates as well as the vice presidential debate, puts Obama's margin at 16 percentage points, the Times said.
The Times noted snap-polls after the second debate indicated an average of 10 percentage points for Obama, smaller than Romney's average 29 percentage-point win in Denver after the first face-off.
The first presidential debate netted Romney a nearly 4 percentage point bounce in head-to-head polls while the second debate didn't bring an appreciable uptick for Obama, the Times said.
Obama could see a 1- to 2 percentage-point bounce following the third debate, but there are some intervening factors, including the debate's pace, the subject (foreign policy) and competing sporting events on other networks, the Times said.
Historically, the Times said, any lift from a third presidential debate was smaller than a bounce following the first two tilts.
