And as if things couldn't get weirder - a Republican got elected to North Dakota's state legislature a month after he died from covid-19
I am not even saying anything about Georgia, but Michigan has stated that most of their votes left, about 2 million, are mail in votes/absentee, and they aren't counting them til today. So, I don't know how you are saying that Biden won't be getting them when most of those votes will probably go to Biden. Same thing in Pennsylvania.
More likely there just not voting at all, we saw similar in a way in the UK. The conservatives won a historic land slide here last year with only 1% more of the vote.
The reason the cons won a landslide wasnt because more voted for them than last time, it was just less were bothered to vote for labour.
