1949 — Harry S. Truman is inaugurated as President

Late breaking spoiler: the Chicago Tribune got it wrong. Truman defeated Dewey, and quite handily, at that. He received 303 votes in the Electoral College to Dewey’s 189 (the remaining 39 votes were won by Strom Thurmond). Harry Truman’s Inauguration was the first one ever to be televised live across the nation.

Truman’s second term as President would largely be concerned with foreign affairs, particularly the newly nuclear bomb enabled Soviet Union and the Korean War. Truman did not contest the 1952 election, having become increasingly unpopular with voters during his second term.
