Also Nevada, New Mexico, Oregon, some of the likely Harris states, have not yet been called. They're close, but it's expected that most of the remaining votes are Harris votes.
This is part of that whole #RedMirage thing we were talking about before the election. The votes don't all get counted right away, and most of the votes that get counted later end up being votes for Democrats.
Once again, it's unlikely this will sway the election, but it's why the vote totals and the popular vote seem so off from what was predicted.
