CBS News and Knowledge Networks have conducted a nationally representative poll of 473 uncommitted voters to get their immediate reaction to tonight's vice presidential debate.
After the first presidential debate, a similar survey showed that more uncommitted voters identified Barack Obama as the winner
Final numbers from tonight's poll have yet to come in, but we do have some early results. (These numbers may change as more respondents complete the survey.) They suggest that once again more voters have responded favorably to the Democratic candidate.
Forty-six percent of the uncommitted voters surveyed say Democrat Joe Biden won the debate, compared to 21 percent for Republican Sarah Palin. Thirty-three percent said it was a tie.
Eighteen percent of previously uncommitted percent say they are now committed to the Obama-Biden ticket. Ten percent say they are now committed to McCain-Palin. Seventy-one percent are still uncommitted.
Both candidates improved their overall image tonight. Fifty-three percent of those surveyed say they now have a better impression of Biden. Five percent say they have a worse opinion of the Delaware senator, while 42 percent say they debate did not change their opinion.
Fifty-five percent say they now have a better opinion of Palin. Fourteen percent say they have a worse opinion, while 30 percent say their opinion hasn't changed.
After the debate, 66 percent see Palin as knowledgeable about important issues – up from 43 percent before the debate. But Biden still has the advantage on this – 98 percent saw him as knowledgeable after the debate. That figure was 79 percent before the debate.
I think polls like this confirm the first impression of Adam (and others) that this debate wasn't a game-changer in either direction, which is fine since a game-changer is what McCain, not Obama, needs.
