was in the aftermath of the 2020 election, when many Americans felt there was overwhelming evidence of voter fraud
The belief in voter fraud was largely because of Trump trying to find a way to lever some electoral votes and win again. This didn’t work because there is no evidence of more then trivial voter fraud, fractional percentages that happen every election. In fact the recounts by Trump allies largely added a handful of votes to Biden’s totals but none changed the vote totals in a significant manner.
One must always cross the Rubicon
Trump had his chance on Jan 6th but lacked the personal courage. He left the group before it reached Congress because he is a coward at heart. He get medical deferments to say out of Vietnam, he avoided Jan 6th, when he was President he didn’t even fire people in person.
