Era III · 1932–1964
The New Deal Order
A coalition of the South, the cities, and labor — built in 1932, cracking by 1948, gone by 1968
No election in the record moves the map like 1932. Herbert Hoover had won 444 electoral votes in 1928; four years and one Depression later he kept 59. Franklin Roosevelt's 17-point victory rewired American politics in a single cycle, and 1936 pushed it further: FDR carried every state but Maine and Vermont, and the county file shows the high-water mark of the Democratic century — 62 percent of the two-party vote summed across all counties, a figure only Lyndon Johnson would come within a point of, in 1964.
The New Deal coalition was a contradiction that worked: white Southern segregationists, Northern Black voters newly moving into the Democratic column, Catholic and Jewish immigrants in the cities, and organized labor everywhere. As long as economics defined the fight, the contradiction held — through the war, through FDR's four elections, and into Harry Truman's astonishing 1948 hold.
National popular-vote margin by election, 1932–1964. An era of decisive verdicts — five double-digit margins in nine cycles — with 1960, the century's closest race, near the end.
But 1948 is also where the crack becomes visible in the returns. Strom Thurmond's States' Rights ticket — a protest against the Democratic convention's civil-rights plank — carried four Deep South states and 39 electoral votes while barely registering outside them. The almanac's county view of 1948 shows the future in miniature: the Democratic Party's Southern wall could be breached from the right, on race, without costing a single Northern vote.
The 1950s look placid in the data — Eisenhower's two landslides were personal rather than partisan, and he broke into the Solid South's rim states, carrying Virginia, Tennessee, Florida, and Texas twice. John Kennedy's 1960 win restored the coalition by two-tenths of a point in the popular vote, the closest race between 1888 and 2000, complicated in the returns by Alabama's and Mississippi's unpledged electors.
Two-party Democratic share in Mississippi, Alabama, and South Carolina, 1932–1964: from 90-percent Roosevelt states to the Goldwater column in a single generation.
Then the era closes the way it opened: with one election that moves everything. Lyndon Johnson's 1964 landslide — 61 percent, the largest popular share in the record — came with a warning attached. Barry Goldwater, running against the Civil Rights Act, won exactly six states: his own Arizona, and the five states of the Deep South, several of which had not voted Republican since Reconstruction. Mississippi gave Goldwater 87 percent. The almanac's swing map for 1964 is the picture of a party system ending: the whole country lurching one way, and the Deep South lurching the other — Mississippi's margin moved 86 points in four years.
