That's the point. Go do something about it now.
If you lived in a suspect-rigged area, such as AZ, find the largest group voicing your concerns and join them. AZ is requesting a new election by Dec 6th.
If your elections went fine, support AZ.
If it's too overwhelming, just focus on your own region.
Local action is national action.
Every local area must continually push for: clean voter rolls, voter ID, paper ballots (no machines), absentee ballots (no mail-in!), hand counted elections, full transparency with observers, with results on election day, and with mandatory record preservation and automatic audits.
