From Salon.com’s War Room:
So far, it appears that most Americans believe that Barack Obama swept the series, winning this debate and finishing 3-0 against John McCain. (4-0 if you count the Joe Biden-Sarah Palin debate.)
CBS News and CNN both conducted polls in the immediate aftermath of the debate, and both showed respondents, by a wide margin, awarding the victory to the Democratic nominee.
Fifty-eight percent of those surveyed by CNN said they believed Obama won Wednesday night’s contest; 31 percent said they thought McCain came out on top. The margin of error was plus or minus four percentage points.
CBS restricted its poll to uncommitted voters, but found similar results — 53 percent of respondents said they thought Obama won, while 22 percent said the same for McCain and 24 percent called it a draw. No word yet on the margin of error there.
