What happens if there's no clear winner in the upcoming Presidential 2020 Election? Short answer – the House selects a President, however each state’s raft of representatives gets only one vote, so all of California gets one vote, just like Montana. Presently there are 25 overall Republican states, 24 Democrat states, and one tied state. But a number of them are only one swing vote away from switching, and they say to expect horse-trading. https://www.foxnews.com/politics/what-happens-if-theres-no-clear-winner Edit: After posting this it came to mind that the "NEW" House, would be the ones voting for the Presidential winner, whom go into the house on Jan 4th (usually  the 3rd which this time is a Sunday), would be choosing the new POTUS. This would be dependent on who the winning Congress Critters who are victorious in their states in the Nov 3 election from either Dem or Repub states.  I'm no Lawyer and I could be wrong so correct me if you've better info on this. Monkey wrenches for everyone...
