Dwight D. Eisenhower Republican Dwight D. Eisenhower Republican The 1956 United States presidential election in Wyoming took place on November 6, 1956, as part of the 1956 United States presidential election.

Wyoming was won by incumbent President Dwight D. Eisenhower (R–Pennsylvania), running with Vice President Richard Nixon, with 60.08 percent of the popular vote, against Adlai Stevenson (D–Illinois), running with Senator Estes Kefauver, with 39.92 percent of the popular vote, a Republican victory margin of 20.2%.

Eisenhower's underperformance relative to 1952 was not unique to just Wyoming, as most of the Mountain West swung a few points against him.

Given the fact that the state's economy relied heavily upon agriculture, this is possibly due to a 5 year long drought in the High Plains, which encompasses parts of Wyoming, Montana, Colorado, and New Mexico.

Estes Kefauver gave one speech in Rock Springs, Wyoming.
