CNN:

Forty-eight percent of voters who watched the vice presidential debate think that Rep. Paul Ryan won the showdown, according to a CNN/ORC International nationwide poll conducted right after Thursday night's faceoff. Forty-four percent say that Vice President Joe Biden was victorious. The Republican running mate's four point advantage among a debate audience that was more Republican than the country as a whole is within the survey's sampling error.

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% said the debate made them more likely to vote for Republican presidential nominee Mitt Romney and 21% said the faceoff made them more likely to vote to re-elect President Barack Obama.

According to the survey, 55% said that the vice president did better than expected, with 51% 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.

CBS:

Fifty percent of uncommitted voters who tuned into Thursday night's vice presidential debate in Danville, Ky., said they see Vice President Joe Biden as the winner over Mitt Romney's GOP running mate Rep. Paul Ryan, R-Wis., according to an instant poll taken by CBS News.

Of the 431 polled immediately following the debate, 31 percent deemed Ryan the winner, and 19 percent said they felt it was a tie. Party-wise it's a switch from last week's presidential debate, which uncommitted voters handed easily to Romney over President Obama.
