Support in the head-to-heads is sharply split along gender lines. Trump leads all five Democratic contenders by double digits among men, while every Democrat leads the president by double digits among women, except Biden, who has an 8-point edge.

The poll shows Trump with an above-water approval rating, with 48 percent of registered voters approving of the job he’s doing and 44 percent disapproving. His disapproval rate is the lowest it’s ever been in the Emerson College poll.

Wednesday’s poll shows only minor differences from the same survey last month, in which Sanders again was the only Democrat to lead the president.

The Vermont Independent, a self-avowed democratic socialist, has repeatedly batted back claims that he is too progressive to defeat Trump, saying that his candidacy will spark a wave of voter turnout that will send him to the White House.

The Emerson College poll surveyed 1,250 registered voters from Feb. 16-18.
