63 – 1872 election: Horace Greeley, the Liberal Republican/Democrat nominee, died on November 29 shortly before the Electoral College vote in December. Three electors voted for the deceased Greeley as pledged, while the other 63 electors pledged to Greeley voted for other persons, with 18 of them casting their presidential votes for Greeley's running mate, Benjamin Gratz Brown, and the remaining 45 scattering their presidential votes among three non-candidates. The three posthumous presidential votes cast for Greeley were rejected by Congress.
