Across the six closest states that went Republican in 2016, he trails Joe Biden by an average of two points among registered voters but stays within the margin of error.
Mr. Trump leads Elizabeth Warren by two points among registered voters, the same margin as his win over Hillary Clinton in these states three years ago.
The poll showed Bernie Sanders deadlocked with the president among registered voters, but trailing among likely voters.
The results suggest that Ms. Warren, who has emerged as a front-runner for the Democratic nomination, might face a number of obstacles in her pursuit of the presidency. The poll supports concerns among some Democrats that her ideology and gender — including the fraught question of “likability” — could hobble her candidacy among a crucial sliver of the electorate. And not only does she underperform her rivals, but the poll also suggests that the race could be close enough for the difference to be decisive.
In national polls, Mr. Trump’s political standing has appeared to be in grave jeopardy. His approval ratings have long been in the low 40s, and he trails Mr. Biden by almost nine points in a national polling average. But as the 2016 race showed, the story in the battleground states can be quite different. Mr. Trump won the election by sweeping Michigan, Pennsylvania, Wisconsin, Florida, Arizona and North Carolina — even while losing the national vote by two points.
Democrats would probably need to win three of the six states to win the White House, assuming other states voted as they did in 2016 — an outcome that is not at all assured.

The poll offers little evidence that any Democrat, including Mr. Biden, has made substantial progress toward winning back the white working-class voters who defected to the president in 2016, at least so far. All the leading Democratic candidates trail in the precincts or counties that voted for Barack Obama and then flipped to Mr. Trump.
As a result, Democrats appear to have made little progress in reclaiming their traditional advantage in the Northern battleground states, despite their sweep there in the 2018 midterms. Respondents in these states said they voted for Democratic congressional candidates by an average of six points, all but identical to their actual winning margins.
Nearly two-thirds of the Trump voters who said they voted for Democratic congressional candidates in 2018 say that they’ll back the president against all three named opponents.
Nonetheless, Mr. Biden holds the edge among both registered voters and likely voters, and even among those who cast a ballot in 2016. He has a lead of 55 percent to 22 percent among voters who say they supported minor-party candidates like Gary Johnson and Jill Stein, and among those who say they voted but left the 2016 presidential race blank. It comes on top of a slight shift — just two points in Mr. Biden’s favor — among those who say they voted for either Mrs. Clinton or Mr. Trump.
Ms. Warren and Mr. Sanders, on the other hand, lose a sliver of Mrs. Clinton’s vote and make fewer inroads among Mr. Trump’s supporters.
