If you read Article 2, Section 1 of the U.S. Constitution, which was later amended through the 12th Amendment, it seems as if the founders of this country anticipated that the “House tiebreaker” process would happen on a fairly regular basis. This would be the case if you had regional parties and more than two major candidates in any presidential election who had enough regional appeal to win electoral votes in a presidential election.
The article allows electors to vote for only two candidates.
