Joe Biden has won and/or is projected to win in Arizona, Michigan, Wisconsin, and Nevada. This would give him exactly 270 electoral votes, the number required to become the president.
In 2016, there were a total of 10 faithless electors (highest since 1912) casting ballots for candidates not chosen by their home states. Assuming Trump wins Georgia, North Carolina, and Pennsylvania. Biden is supposed to get 270 electoral votes and Trump is supposed to get 268 electoral votes. In this scenario, we would need only one faithless elector from Arizona or Nevada or Michigan, or Wisconsin to cause a tie, 269 to 269.
What penalties if any can be imposed on faithless electors specifically from Arizona, Nevada, Michigan, and Wisconsin? Can legislatures in these states specifically appoint someone to be a faithless elector at this point or after all the votes are counted?
