I believe most of the accusations about 2020 were centered in places where the Democrats were in power like Philadelphia and its suburbs.
Control of the WH is immaterial because all voting is controlled by the states or local municipalities.
Another part is that the Republicans were much more prepared this time to stop the alleged fraud before it happened. They had lawyers ready to protest immediately when election judges were locked out of counting rooms or when counting stopped. They made sure they had enough election judges for all precincts and sometimes they set up cameras to count the number of voters entering the site.
Perhaps your point about polling is still the best answer
Sure, but the FBI and DOJ still have the authority (and mandate) to detect and prevent election fraud, and certainly to the scale that was alleged.
Deciding between the effort required for a political opponent to run a massive multi-state voter fraud conspiracy under your nose and the effort required for an over-the-top personality to make a wild accusation that was never proven in court, I think we can consult Occam’s Razor.
I believe that many of the court battles revolved around issues like "standing", not whether there was any substance to the matter. So it's not really fair to put any value in whether the accusations were "proven in court" because the courts never focused on the accusations themselves.
I have no real desire to work through all of this again. It was 4 years ago. Alas, all of your numbers aren't so convincing to me. As we saw with this last go around, you could find numbers from pollsters that predicted either outcome. So I don't know where you got them and I'm not interested in parsing whatever you have to say.
I do know that many of the "merits" you cite were never litigated. Were there any cases where the court granted discovery? So how can anyone guess at what a court would decide about the matter? Many of the news articles I read at the time suggested that the courts were just not interested in opening up cans of worms.
