Vice President Harris is leading former President Trump by 1 percentage point nationally among likely voters, according to a new poll.

The Marquette University poll, released Wednesday, found Harris has 48 percent while Trump narrowly trails with 47 percent. Four percent said they would vote for someone else, and 1 percent said they would not vote for president. 

When independent candidates Robert F. Kennedy Jr. and Cornel West, Green Party candidate Jill Stein and Libertarian Party candidate Chase Oliver were included, the gap between the two widened slightly.

The survey shows Harris receiving 44 percent of support from likely voters in that case, with Trump at 41 percent. Nine percent supported Kennedy, 2 percent each were in favor of Oliver and West and 1 percent favored of Stein.

Harris maintained the same favorability rating the survey found her earning in July, at 47 percent, but her unfavorability rating spiked by 2 percentage points, with 52 percent of registered voters disapproving in the new poll. Two percent said they haven't heard enough to decide. 

Trump's unfavorability rating also rose 2 points in that period, climbing to 55 percent in the new poll, while his favorability rating fell slightly from 45 percent to 44 percent. One percent said they haven't heard enough to decide.

Fifty-three percent of voters think Harris will definitely or probably win, while 47 percent believe the same of Trump.

Democrats also have a narrow edge in national support in congressional races, according to the poll, leading Republicans by 2 percentage points. Fifty-one percent of likely voters said they will vote for the Democratic candidate, while 49 percent said they will vote for the GOP candidate.

The survey was conducted Oct. 1-10 with 886 registered voters nationwide. The poll has a margin of error of 4.3 percentage points. For likely voters, the sample size was 699, with a margin of error of 4.7 percentage points.
