It did not endorse candidates other than Eisenhower, but he paid it little attention after he had won, and it failed to maintain its impressive starting momentum. Instead, it energized the conservative Republicans, which led finally to the Barry Goldwater campaign of 1964. Longtime Republican activists viewed the newcomers with suspicion and hostility. More significantly, activism in support of Eisenhower did not translate into enthusiasm for the party's cause. Results On election day, Eisenhower won a decisive victory by winning over 55% of the popular vote and carrying 39 of the 48 states. Stevenson did not win a single state north of the Mason–Dixon line or west of Arkansas; he did succeed in winning back the four states which Strom Thurmond had won at the previous election, but lost all but five of the states that Truman had won that year. Eisenhower took three Southern states that the Republicans had won only once since Reconstruction: Virginia, Florida, and Texas. Despite the Republican win in Florida, that year was the last time that a Democrat has won Collier County before southwestern Florida was turned into a growing Sun Belt Republican stronghold, and it was also the last time that a Democrat has won Aiken County, South Carolina, before the "Solid South" would collapse in the wake of the Civil Rights Movement. That year was also, however, the last time a Republican won Yolo County, California or the Native American Rolette County, North Dakota, and the last until Donald Trump in 2016 that the Republicans won Pacific County, Washington, or Swift County, Minnesota. It was the last time the Republicans won Missouri until 1968 and the last time that a Republican won the election without Kentucky. Stevenson's 700-vote win was the smallest percentage margin in any state since Woodrow Wilson had won New Hampshire by 56 votes in 1916. Eisenhower won in 21 of the 39 cities with a population above 250,000. He won in six of the eight largest Southern cities. The election was the first in which a computer, the UNIVAC I, was used to predict the results; it came within 3.5% of Eisenhower's popular vote tally and four votes of his electoral vote total.
