Wisconsin Rep. Paul Ryan won the Thursday vice presidential debate, according to a new CNN/ORC International poll, but not by much.

48 percent of those who saw the debate thought the Republican won, while 44 percent said Vice President Joe Biden won.

Here's more from CNN:

"Half of all debate watchers questioned in the poll said the showdown didn't make them more likely to vote for either of the candidates' bosses, 28 percent said the debate made them more likely to vote for Republican presidential nominee Mitt Romney and 21 percent said the faceoff made them more likely to vote to re-elect President Barack Obama.

"According to the survey, 55 percent said that the vice president did better than expected, with 51 percent saying that the congressman from Wisconsin performed better than expected.

"By a 50-41 margin, debate watchers say that Ryan rather than Biden better expressed himself.

"Seven in ten said Biden was seen as spending more time attacking his opponent, and that may be a contributing factor in Ryan's 53-43 advantage on being more likable. Ryan also had a slight advantage on being more in touch with the problems of average Americans."
