What about all those people that claimed to have definitive proofs on twitter and on television and then it turned out that they had no knowledge of the facts?

The broad statements might have some supporting fact but along the way some (Brian Stelter I think) have theorized that Trump was a Russian agent since the soviet union.

I don't doubt that Biden won, but it's not like there's zero evidence for voter fraud. A USPS employee was recently arrested for trying to take absentee ballots out of the country, another in PA said that he was told to back date ballots received after the election so they could still be counted, and they've also found ballots in the trash that were mostly for Trump. He's exaggerating, but he's not just making things up either.

With 150 million ballots both sides could easily find individuals that may have had legitimate issues with voting. As to something systematic they don’t seem to have found anything.

Sure, but just listing those headlines without any details is quite reductive.

That USPS employee had a full bag of over 800 pieces of mail, 3 of which were ballots [1]

I haven’t been able to find a specific story about ballots in the trash after Election Day. I did find a story from NJ [2] and one from KY [2] about USPS dumping mail in the trash, and some of that mail was empty ballots being sent out to voters. Do you have the specific story you are talking about?

The PA employee wasn’t asked to backdate ballots, he was asked to collect ballots arriving after Nov 3 in a separate bin, and he feared that his bosses would backdate them [4]. This was also in a town of 5000 people. Here is what he said:

“On Wednesday the fourth, we checked in at the time clock,” the anonymous postal worker told Project Veritas chief James O’Keefe. “The postmaster then told us that if we were to find any ballots on our routes that day, we were to collect them, keep them separate in a hod, which is what we call our plastic bins, bring them back, and then we would put them in another hod and then they would send them to be counted.”

“The postmaster (James Malia) and the supervisor (William Wood) did not say that we’re going to, we’re going to backdate them,” the whistleblower clarifies, but “I was firmly of the belief that they were going to be backdated. We’re always hit with the Hatch Act. You know, you can’t talk about politics, you can’t influence people. On one occasion, the postmaster James Malia had gone, had attacked a carrier who had expressed support for Trump.”

...says he overheard Malia chide Wood for having “postmarked one of the ballots for the fourth, instead of the third, because they were supposed to put them for third”.
