The AP has called Wisconsin for Biden, as his margin over the president continues to grow as workers report on last few ballots left in Milwaukee. The New York Times believes Michigan and Nevada will also go to Biden, North Carolina won't, and Pennsylvania and Georgia are still too close to call. So as of now, the map looks like this:
Nevada won't release any new numbers until 9am PST tomorrow (18:00 UTC, 11am in Chicago), but Biden's lead seems insurmountable at this point. North Carolina's secretary of state said he expects to announce the winner later today. No word on when Michigan and Pennsylvania will finish counting; most sources say Friday at the earliest.
In other news, we've officially counted 139.8 million votes, blowing past the 137.1 million cast in 2016. It's the largest number in American history and we still have over 2 million to go. Also, win or lose, Joe Biden has received more votes for president (over 70 million) than anyone else in history. That's something.
