Welcome to 2020: Obstacles for Trump and a wide-open Democratic race, poll finds

A third of Republicans and GOP-leaning independents oppose President Donald Trump for the party's nomination to a second term and 56 percent of all adults said they wouldn't consider voting for him -- two hurdles in his quest for re-election next year.

But a potentially crowded Democratic field shows no sign of a clear front-runner across the aisle in this ABC News/Washington Post poll, and there's deep division on priorities for the election season ranging from the relative importance of electability to key issues.

In short, with 21 months to go, 2020 is anyone's game.

The nomination comes first. Thirty-two percent of Republicans and Republican leaning-independents said they'd like the party to nominate someone other than Trump as the GOP candidate for president in 2020.

Among mainline Republicans -- excluding independents who lean toward the party -- 27 percent want someone other than Trump. Opposition to Trump runs as high as 41 percent of women, 42 percent of independents and 49 percent of moderates within the ranks of Republicans and GOP leaners.

Sixty-five percent of leaned Republicans and 71 percent of mainline Republicans stick with Trump, plenty enough for him to secure the nomination. But the level of potential defections is high enough to raise concerns in his camp.

So is the broader finding in which 56 percent of Americans said they definitely wouldn't vote to re-elect Trump. That's twice as many who said they'd definitely vote for him, 28 percent. A smaller share said they'd consider it, 14 percent. Results are identical among registered voters.

Opposition to a second Trump term is significantly higher than former President Barack Obama encountered, peaking at 46 percent in Oct. 2011. Trump's support in his base is more solid, with 70 percent of Republicans who said they'll definitely vote for him, compared with 58 percent of Democrats for Obama in 2011. But Trump falls short when it comes to the often swing-voting independents: Fifty-nine percent said they wouldn't consider him. Forty-seven percent ruled out Obama.

Trump also suffers among women, which is unsurprising given the wide gender gap in his job approval rating -- just 27 percent among women versus 49 percent among men -- as reported Friday. Nearly two-thirds of women in this survey, produced for ABC News by Langer Research Associates, said they definitely wouldn't vote for him, compared with 48 percent of men. That includes 94 percent of Democratic women, 62 percent of independent women and 18 percent of Republican women. It's 10 percent among Republican men.

Other groups ruling out Trump include those without a religious affiliation, 73 percent, 77 percent of nonwhites, 88 percent of Democrats and 92 percent of liberals. Strong backing for Trump is comparatively lower, peaking demographically at 60 percent of evangelical white Protestants and reaching 70 percent only among Republicans and approvers of his work in office.

Among the risks to Trump is the third of leaned Republicans who want the party to nominate someone else. Were Trump the candidate, just 12 percent in this group said they'd definitely support him. Forty-three percent would consider it -- and another 43 percent said they would not.

Of course, such evaluations are hardly set at this point. In July 2015, 61 percent of registered voters said they would definitely not vote for Trump in the 2016 election, including three in 10 Republicans, a far cry from the final result.

This ABC News/Washington Post poll was conducted by landline and cellular telephone Jan. 21-24, 2019, in English and Spanish, among a random national sample of 1,001 adults and 893 registered voters. Results have a margin of sampling error of 3.5 points, including the design effect. Partisan divisions are 32-24-37 percent, Democrats-Republicans-independents.

The survey was produced for ABC News by Langer Research Associates of New York, N.Y., with sampling and data collection by Abt Associates of Rockville, Md. See details on the survey's methodology here.
