Fox News poll:
In a head-to-head presidential matchup, Biden is up by 49-40 percent over Trump, a lead that is outside the poll’s margin of sampling error. Another 11 percent would vote for someone else or are undecided. Last month, Biden was ahead by 49-41 percent.
Also: Biden’s advantage grows to 25 points, 57% to 32%, in close counties (where Hillary Clinton and Trump were within 10 points in 2016).
