Oprah and Obama campaigned in Iowa, South Carolina, and New Hampshire over the weekend.
WASHINGTON (CNN) - Oprah Winfrey's campaign swing last weekend with Democrat Barack Obama was greeted with record-breaking crowds and an equal amount of speculation over how much impact the media mogul might have on the White House race.
After all, Oprah has sent several books to the top of the bestseller list. Why couldn’t that magic touch take a candidate to the top of the polls?
But a new survey out Monday night shows Winfrey's endorsement is unlikely to nudge Obama higher in the polls -– and could potentially hurt the Illinois senator.
According a New York Times/CBS News poll released Monday, only 1 percent of Democrats polled reported that Winfrey's endorsement would make them more likely to support Obama, while 14 percent said they would be less likely to vote for the candidate because of Winfrey's support.
Meanwhile, rival Hillary Clinton's biggest celebrity endorser - her husband Bill Clinton - is likely to have more of an impact. The poll suggests 44 percent of Democrats are more likely to support the New York senator because of her famous husband, while only 7 percent are less likely to do so.
In fact, the former president is such a campaign asset that according to the poll, roughly as many Democrats are supporting the New York senator because of her husband as are supporting her because of her experience. Twenty-six percent of Hillary Clinton's supporters name Bill Clinton as the top reason they are backing her, while 23 percent say her own experience is the biggest factor.
