Anecdotal data is wholly irrelevant when you have laws upholding the results and should have no bearing on convincing you of one or another thing.

Yes, we know that every election has some fraud. A lot of it is unintentional and a lot of it has been perpetrated by republican voters.
There were fewer than 475 cases of voter fraud found in the 2020 election. https://fortune.com/2021/12/14/trump-voter-fraud-investigation-biden-battleground-states-only-475-potential-voter-fraud-cases/

The ultra-conservative think tank The Heritage Foundation has recorded just 1.438 proven instances of voter fraud going back to the 1990s.

There has been an attack on our country by a sitting president to destabilize the people's trust in the principle element of democracy. It has worked extremely effectively as nearly everyone will now question how valid an election really is - the kernel of doubt has been sown. Yet there was zero Z.E.R.O. reason to question the results of the 2020 election.

Trump and his allies had claimed there was voter fraud because the polls prior to the election indicated he was in the lead while the results of the election contradicted the polls. There was also the previously known and reported and anticipated timing of events where mail in ballots were counted in bulk at odd times. Everyone knew the votes would be counted in chunks and that one candidate would quickly pull ahead of the other. We even knew that a lot of republicans weren't going to vote because it was already anticipated (for no reason) that the election would be rigged. As entirely fictional reports of voter fraud made their way through the zeitgeist, they grabbed onto these stories and presented them as fact with zero evidence to back them up (looking at you pillow guy). The cases were thrown out of court because the lawyers had absolutely no evidence to present to the judges.

Anecdotal stories are irrelevant when the sitting president of the United States is known to have fucked this country over. He's an evil narcissist and anyone who believes him to be anything else is a fool participating in his intentional dismantling of our democracy for his personal gain and pleasure.

You shouldn't be "thinking" there wasn't enough fraud to sway the election. You should know this to be 100% factually true just as you know it to be 100% factually true that the moon is a sphere. What's on or inside the moon is certainly up for debate ;-)
