New Jersey loved Warren Harding.
In the 1920 presidential election, Harding won 68% of the vote in New Jersey. He won all 21 counties, and the GOP won 59 of the state’s 60 State Assembly seats.
Calvin Coolidge took 62% of the vote in New Jersey in 1924, and Herbert Hoover carried the state with 60%.
Franklin Roosevelt won New Jersey four times, although only once by an impressive margin.
In 1932, his margin against Hoover was just two points – 49.5%-47.6%. Hoover won 17 counties, with Roosevelt carrying Hudson, Middlesex, Passaic and Warren counties. Jersey City mayor Frank Hague and Middlesex County Democratic boss David Wilentz put him over the top.
Roosevelt won New Jersey with 60% in 1936, although Alf Landon carried Morris, Monmouth, Ocean and Sussex counties.
In 1940, Wendell Willkie held Roosevelt to a 52%-48% win. Willkie won ten counties: Bergen, Cape May, Essex, Hunterdon, Mercer, Monmouth, Somerset, Sussex Ocean, and Union.
Roosevelt carried New Jersey in 1944 by 50%-49% margin against Thomas Dewey. Dewey won eleven counties – the same ten Willkie did, plus Warren.
Dewey beat President Harry Truman in New Jersey in 1947, wining the state by a 40%-46% margin. Truman won Hudson, Passaic, Middlesex, Mercer, Camden and Salem counties.
Dwight Eisenhower easily carried New Jersey in his two presidential bids.
He defeated Adlai Stevenson with 57% in 1952, winning everywhere but Hudson, Mercer and Camden counties.
Eisenhower swept all 21 New Jersey counties in 1956, defeating Stevenson by a 65%-34% margin.
