I've seen the 80%, but also that 78% of Republicans think that there were fraud or other irregularities.
Yeah, that's why I am not sure what to make of it.
The other problem is that it's a process involving 160 million votes, in a variety of 50 states, etc, and it's run by county. There's always going to be mistakes.
(I work in systems and we process millions of transactions -- when you dig into the numbers, you will find issues sometimes in the realm of 2000 cases coming through the pipeline, as an example, that are causing something to throw a particular error; but compared to the amount of cases/transactions we process, that number that sounds so large to a single person is actually very very tiny compared to everything that did work correctly and sometimes not worth spending millions of dollars to tweak the system for, they can handled in other ways, manually, when they do come to light. And yes, they get caught and reported for investigation.)
Basically, I am sure either side will find mistakes in how a small number of ballots was processed that could result in a change to the numbers. When they run recounts, sure, the tallies typically end up being adjusted in some way. But usually not in a meaningful way. (Florida 2000 was one example of where a race was close enough and down to one state, that it became a focal point for investigation. But there have been occasional local/smaller contests that were closer, since the number of votes and thus the range of possible outcomes was smaller. But again, they have processes in place for recounts.)
So the question is:
1. Does the system function on the broad scale properly?
2. Are the mistakes in ballot counting accidental / due to chaos, or are they purposeful?
3. On what scale of magnitude are these mistakes occurring?
Trump is screaming, "FRAUD! PURPOSEFUL CHEATING! MISTAKES ALL BENEFIT ONE SIDE! ELECTION WAS LOST BECAUSE OF THEM!"
The reality so far is, "SYSTEM WORKS! MISTAKES BENEFIT BOTH SIDES! ACCIDENTAL FLAWS OVERALL! NOT EVEN CLOSE TO CHANGING RESULTS!"
I just find it despicable that he has no basis to make these claims, currently, but assaults the process and impugns his opponents. Maybe that can be an option AFTER investigating, if warranted, but he had no actual evidence at the time of his claims. It's even more gross when he attacked the state's mail-in ballot process in PA (for example)... but only in the counties he lost, while being apparently just fine with the mail-in process in the counties he won.
