User:TransUtopian/Electoral College closeness

List of United States presidential elections by Electoral College closeness However, prior to the passage of the 12th Amendment, electors cast two votes for president, with the vice president simply being the runner-up who received votes from over 50% of the number of electors. The president would be the person who got a majority of electors to vote for him and who got the most number of votes

Thus, for elections prior to 1804, if two candidates got above 50% of the electors, the margin of victory is the victorious candidate's margin over the other candidate who got above 50% of the electors. As it happens, of the four elections prior to the 12th Amendment, two involved two candidates getting above 50% of the electors: 1792 and 1800.
