What happens in the event of a tie for a 12th amendment House vote?
Evan McMullin is running for president, hoping to be elected via the 12th amendment, which would require him to receive at least 1 EC vote, and there to not be a candidate that receives the minimum 270 votes. In that event.
The person having the greatest Number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice.
Of particular note is the vote state by state, through members of the House. Hypothetically, if a state had an even number of representatives, and was divided as to whom to support such that a majority was not achieved, how would their vote be cast for president?
