PedoJoe and his minions can try and cancel the election, but it would have no meaning. We don’t have a national election we have 50 state elections - 51 if you include DC. You might get some of the slavishly Rat states to try to do it. There’s no means to cancel an election and have it be legal. It would be a true coup.
Trump will be convicted long before the election and will not be allowed on the ballot in enough states to win the election. The election will effectively be uncontested. I doubt Biden will be on the ballot either. The Dems will probably go with Big Mike Obama so Black voters don’t leave the plantation over passing over Camel Toe.
