If there is no one with a majority on counting day due to contested EVs or what ever, the election goes to the House and each State gets one vote for President. Assuming no defections, Trump wins since Rs hold the majority of House delegations. Similarly, the VP choice goes to the Senate, and since Rs hold the Senate. This takes place on Jan 6. So the only way Biden wins is by stealing the election NOW. Pelosi is not a part of that process, she only gets to be President after she assassinates Biden and Harris after they’re sworn in.
The election court battles have to be done before December 14th so the electors can transmit their votes to Congress.
and since the Rs hold the Senate, they pick Pence.
Thanks for that explanation.
