So just cleaning up loose ends... Final electoral college: 306-232 (same as 2016 if you ignore faithless electors).
Popular vote count:
Biden: 81,283,495
Trump: 74,223,753
Biden wins popular vote by 7 million votes, or 4.5 percentage points.
One way this election was just a little closer than 2016 was in the minimum number of votes that would have to change for Clinton to win (~78k) versus the minimum for Trump to have won (~65k) in the electoral college.
Of course 2020 elections aren't totally over. Control of the Senate is still up in the air depending on the election in Georgia happening now.
