This image is a modification of PartyVotes-Presidents.png with a highlighting of the 14 Presidents who had served as Vice President. Of these 14, only 5 were elected directly into the Presidency (with 2 of these achieving re-election), with the other 9 filling a vacancy (8 due to death, 1 due to resignation). Of these 9, re-election was achieved by 4. Nixon is unique in that he is the only one to become President with a gap after having left the office of Vice President. Ford is unique in that he was never elected as either President or Vice President. (This was identified as a factor in him losing his bid for re-election.)
