The Joe Biden-Kamala Harris ticket is ahead of the Donald Trump-Mike Pence ticket by a 51-46 percent margin. That 5 percentage-point advantage sits right at the margin of sampling error of the latest Fox News survey, taken after the Democratic and Republican national conventions.

Majorities of likely voters have a positive opinion of Biden and trust him over Trump on coronavirus, Supreme Court nominations, and uniting the country -- and that nudges the former vice president just over 50 percent in the presidential race.

The national survey, released Sunday, is the first Fox News has conducted among likely voters this year and the first time it included running mates in the vote preference question.
