Incumbent President Lyndon Johnson overall won Florida against Goldwater by 42,599 votes, a margin of 2.30%, or a swing of 5.32% from the 1960 result. Increased registration of black voters – it had reached 51% by the time of the election – was crucial to Johnson regaining Florida: in the northern counties of Lafayette and Liberty where no blacks were registered, swings toward Goldwater reached over 100 percentage points. Florida was the second-closest state win by Johnson after Idaho. , this is the last election in which the Democratic candidate carried Charlotte County.
