Notes:

Monroe ran virtually unopposed, though a single vote for John Quincy Adams (then Secretary of State) was cast by one elector. (The belief that this was to ensure that George Washington remained the only president elected unanimously by the U.S. Electoral College seems to be a myth.)

235 electors were appointed, but only 232 votes were cast due to the deaths of electors from Mississippi, Pennsylvania and Tennessee.
