The Democrats will not concede. They will never graciously concede a loss again in a presidential election. Their new strategy is always sue, always argue, always block. Start riots, start fires, start rumors, start investigations. Burn everything and everyone whenever you can.
Trump will win on election night, but the Dems will take months, counting & generating mail in votes to contest the election up until January, at which time they will declare Biden the winner. Biden will eat applesauce to celebrate and the war will begin.
