California uses mail-in ballots. They count the votes for these ballots up to seven days after the election but Harris was declared the winner when the polls closed and I guess all the other ballots maybe get counted? But it was a lot more in 2020. 2024 Harris 5,722,129 Trump 3,984,704 2020 Biden 11,110,250 Trump 6,006,429 It just looks weird.
