Trump's numbers in a potential matchup with Winfrey, who launched Oprahmentum with a stirring speech at Sunday night's Golden Globes, fall in line with his mostly dire approval ratings, which, according to Gallup, was at 37% last week.
Winfrey would start a campaign, which she's said to be "actively thanking" about, but not actively pursuing, with a 64% approval rating and less than a quarter of voters with an unfavorable take. Numbers that strong would likely take a hit once Winfrey started asserting policy positions.
The poll's partisan breakdown offers a more familiar picture. Not even the odd specter of a Trump-Winfrey celebrity showdown could pry voters off their poles. Winfrey has the support of 91% of Democrats, while Trump would have the backing of 85% of Republicans.
Winfrey, however, makes significant inroads with white voters, according to the new poll. Where Clinton lost them by 20% points, Trump and Winfrey are about even, with the President narrowly edging the potential challenger, with 45% to her 44%.
Among political independents, Winfrey also enjoys a modest lead, 46% to 37%, with 17% undecided.
The consensus among Democrats is a bit more cautious.
Simply put, most believe she could win and would happily fight on her behalf, but others worry about Winfrey's inexperience in campaign politics. And for a party still trying to sort out a winning (and unifying) message, questions over where exactly she stands on the major issues of the day linger ominously over the conversation.
Trump has also weighed in, telling reporters Tuesday during a Cabinet Room meeting on immigration, "Yeah, I'll beat Oprah."
"I did one of her last shows," he added. "She had Donald Trump -- this is before politics -- her last week and she had Donald Trump and my family, it was very nice."
A presidential campaign, much as it did with old pal Hillary Clinton, would likely see a change in his chipper tone.
The poll, conducted from January 8-10, surveyed 1,092 registered voters. The margin of sampling error is plus or minus 3 percentage points.
