Not many chances to see a one term Prez up close.
This particular one term is rather historic in terms of how rare it is. I was thinking about how many situations there have been when a president is elected following a president of the other party, serves a single term, gets his party's nomination for reelection, and loses. Those criteria are specifically intended to exclude a situation where a president is a "continuation" of another president from the same party (e.g., GHW Bush as a continuation of Reagan or Taft as a continuation of T. Roosevelt), presidents who succeeded to the office due to death or resignation and failed to win re-election (John Tyler and Gerald Ford, plus some others), presidents who pledged to serve only one term (Polk, Buchanan, and Hayes), or presidents whose party denied them re-nomination (Franklin Pierce).
If you take it that way, there are only four presidents, by my count, who fall into this category, and depending on how you count, it could also be three (if you exclude JQ Adams) or five (if you don’t view John Adams as a continuation of Washington):
—John Quincy Adams is not really a continuation of the 24 years of presidents from the Democratic-Republican Party (Jefferson, Madison, and Monroe). That party largely fell apart by 1824 and Andrew Jackson is usually seen as the leader of the successor party. Adams was elected by the House of Representatives and lost his bid for re-election in 1828.
—Benjamin Harrison defeated Grover Cleveland's bid for re-election in 1888, served one term, and then lost his own re-election bid to Cleveland in 1892.
—Jimmy Carter came after eight years of Republican administration (Nixon/Ford) and lost his re-election bid to Reagan.
—And, of course, Trump.
