At a campaign stop in Alexandria, Va., on Feb. 10, 2008, he brought up the negative opinions some people have of Clinton, who is well known to most voters from her time as first lady.
"I think Sen. Clinton starts off with 47 percent of the country against her. That's a hard place to start if you want to win the election," he said.
Pollsters regularly ask voters whether they rate candidates positively or negatively. Indeed, Clinton's negatives are consistently higher than Obama's, but different polls show her at different levels.
We looked at the times the USA Today /Gallup Poll asked voters whether they had a favorable or unfavorable opinion of Hillary Clinton, going back to January 2007. Her negative percentage fluctuated between 40 and 52, but the average of 21 polls came out to 47.
ABC News and the Washington Post have asked the question at least four times since January 2007. Her unfavorable ratings on that poll came in between 48 and 40, with an average of 44.5. CNN polled four times and found unfavorables between 39 and 44, with an average of 41.5.
Obama's unfavorable ratings tend to be well under 40 percent. In several polls, his unfavorable ratings are in the 20s.
Not every poll rates her unfavorables consistently as high as 47 percent, and poll numbers are always a little bit squishy. But, the USA Today /Gallup Poll has polled often on Clinton's unfavorables, and the average of 21 polls puts her negatives at 47 percent. We find that to be about as solid a poll figure as you can have, so we find Obama's statement True.
