FDR was not long dead before the US ratified the XXII Amendment to the Constitution, providing that nobody might be elected president more than twice, or more than once if he had served more than two years of someone else's term. Any long-serving member of the House of Representatives has become such by standing for election every other year; any long-serving senator by standing every six years. In some cases (think of Strom Thurmond) the election seems to be more or less a formality; but people do turn out and vote.
