President Donald Trump and former Vice President Joe Biden are racing toward Election Day with Biden in Pennsylvania and Trump Michigan, Iowa, North Carolina, Georgia and Florida on Sunday.
Vice President Mike Pence is in North Carolina and Sen. Kamala Harris, D-Calif., is in Georgia and North Carolina.
In the season's final ABC News/Washington Post polls, the pandemic versus the economy defines the presidential contest in two key battlegrounds, with Florida holding firm to its toss-up status while Biden leads slightly in Pennsylvania.
There's little change in either state. In Florida, Donald Trump has 50% support among likely voters to Biden's 48%; it was 51%-47% in an ABC/Post poll Sept. 20. Trump won the state by 112,911 votes out of more than 9.4 million cast in 2016.
In Pennsylvania, the race stands at 51%-44%, Biden-Trump, a 7-point advantage for the Democrat; that compares with a 9-point margin late last month. Here, Trump's 2016 win was even narrower: 44,292 votes out of nearly 6.2 million cast.
Counting the votes “might take some time in this election … and everyone watching at home should know that it is not a sign that anything has gone wrong,” said ABC News Chief Anchor George Stephanopoulos on "This Week" Sunday.
