RICHMOND, Va. (NewsNation Now) — The Associated Press called the 2020 presidential race in Virginia for Democrat Joe Biden early Tuesday night.

However, as of 10:30 p.m. EST, Trump led the state by more than 100,000 votes.

Here is the AP’s explanation as to why it declared Biden the winner of Virginia:

The AP declared Democratic nominee Joe Biden the winner of Virginia at 7:31 p.m. EST, after results from early returns and an AP survey of the electorate showed the former vice president had beaten President Donald Trump in the state.

While only about 10% of the vote had been counted statewide, completed counts in a representative selection of precincts in communities across Virginia showed Biden comfortably ahead of Trump.

Those results matched data from AP VoteCast and an analysis of early voting statistics. The survey found Biden with a substantial lead in the state. VoteCast, the AP’s wide-ranging survey of the American electorate, captures voters’ choices and why they made them.

Virginia was once solidly Republican, with President George W. Bush winning there as recently as 2004. But explosive growth in northern Virginia’s Washington, D.C., suburbs has led to an influx of increasingly diverse and Democratic-leaning voters who have helped tip the balance of power.

Democrat Hillary Clinton won Virginia by more than 5 points in 2016. The state has a Democratic governor. And in 2019, Democrats took control of both chambers of the Legislature for the first time in decades.

When reached for further comment, an AP spokeswoman said: “AP looks at precincts reporting, expected votes, voting percentage received, historical data and data from the VoteCast surveys to make calls. We have our own team of race callers and vote counters counting the vote.”
