Trump leads Biden 45% to 41%, while 14% of voters are unsure, the poll said.
Forty-two percent of independent voters back Trump and 36% back Biden, the poll said.
Both Trump and Biden maintain the support of the majority of their parties’ voters, receiving 86% and 81% support, respectively, the poll said.
However, a majority of voters believe that neither man should run for president, the poll said. More than two-thirds of voters, 69%, think that Biden should not run for reelection, and 59% feel the same way about Trump.
Trump also leads the pack of Republican presidential hopefuls, garnering 58% support, the poll added.
Trump is followed by Florida Governor Ron DeSantis at 14% and businessman Vivek Ramaswamy at 7%, according to the poll.
The poll surveyed 2,982 voters between October 4-7 and has a margin of error of plus-or-minus 1.8 percentage points.
