Forty-six percent of registered voters in the Oct. 25-28 survey say they'd cast their ballots for Biden if the election were held today, the same support the former vice president garnered in a poll conducted earlier this month.

By contrast, 42 percent of registered voters said they would vote for Trump.

The survey found 49 percent of likely voters said they'd choose Biden as their preferred presidential candidate while 45 percent of likely voters said the same of Trump.

"Biden remains ahead in our poll and is capturing the segment of undecided voters who are more likely to vote, giving him a six-point lead if you look at the combined horserace with leaners," Dritan Nesho, lead pollster at HarrisX, told Hill.TV.

"Biden's strength is coming from suburban voters, in particular women and retirees, who have moved away from Trump and do not support him to the same extent as they did in 2016," Nesho added.

The Hill-HarrisX poll was conducted online among 2,824 registered voters and among 2,359 likely voters. It has a margin of error of 1.85 percentage points and 2 percentage points.
