Assuming we end up with a contested election and nobody gets to 270.

Is it one vote per state or one vote per state for the house and one vote per state for the Senate?

So you have many Congressmen/women from a single state. Who gets to decide the vote? You have two Senators from each state, Who gets to decide the vote?

I undestand there are 30 "Republican" States but not sure how they calculate that.

I can see the Republicans screwing Trump even though it will destroy the Republican Party.
