The only ones calling foul in the most inspected, secure election in US history are a bunch sore losers who care more about keeping power than the country they supposedly want to serve. The will of the people spoke by 8 million votes. There is no evidence of voter fraud except of a tiny number of cases (mostly by members of the Party of Trump) who were caught and whose votes would not have affected the election outcome if they hadn't been.
Removing Liz Cheney from POT leadership in the House and the censuring of legislators around the country by the POT are proof that the lying about elections is a requirement for the POT.
The partisan clown show in Arizona is a testament of the commitment of the Party of Trump to destroying faith in our elections to keep a corrupt group of oligarchs in power. This is how fascism takes hold: destroy faith in the press, destroy faith in democratic institutions, and put a populist strong man in power who claims only he can deliver what people want by welding unlimited power.
