The survey, published Wednesday, shows that Kaine has a 23-point lead over GOP nominee Corey Stewart among likely voters.

The poll found that Kaine has the support of 88 percent of Democrats in the survey and leads Stewart by better than a 2-to-1 margin among independents polled who have determined how they will vote.

Stewart, meanwhile, had the support of 66 percent of Republican or Republican-leaning voters who participated in the survey, which was conducted from July 10-30 and surveyed 802 adults. The poll reports a margin of error of 3.59 percentage points for the sample of likely voters.

The poll also found that Kaine is winning “every key demographic category,” including female, male, minority and white respondents. Twenty percent of likely voters remain undecided, according to the poll.

Stewart has previously been accused of ties to white nationalists. In 2017, he also reportedly praised Virginia’s decision to secede from the United States at the onset of the Civil War.
