According to Wikipedia, about 155.5 million people voted in 2020 and so far, there are about 150.2 votes counted this time (98% of votes counted). They say that in 2020 we had a 66.6% turnout, but until all the votes are counted, we don’t have a turnout number yet. That said, it seems on track to be a little lower than 2020, although not by a huge margin.
Where did you get that 11 million number? Vote totals so far are a little more than 5 million short of 2020. Everyone keeps talking about 11 million, 15 million, 20 million people who stayed home and I think it’s frankly a way to cope with the hard and gross truth that the country shifted right. Some people stayed home this year, but from all the sources I can see, it’s nowhere near 11 million, and the fascist candidate increasing his vote totals every year is very alarming. I get people who don’t want to face that. It’s scary as hell, especially if you’re in an out group. In my traditionally deeply blue state, the split gap between Harris and The Fanta Menace was like 55/45. That’s WAY too close for comfort and while people staying home is a problem, it’s not the main problem this time around.
