Harry S. Truman defeated Republican Thomas E. Dewey.

Historical background

The roots of the 1948 election date to 1940, when Pres. Franklin D. Roosevelt decided to run for an unprecedented third term as president. He was challenged unsuccessfully by his vice president, John Nance Garner, and eventually chose as his running mate Henry A. Wallace, Roosevelt’s secretary of agriculture. In 1944, when Roosevelt decided to seek a fourth term, party conservatives, especially Southerners, opposed Wallace’s renomination. Truman, a respected U.S. senator from Missouri who was admired by the public at large, was nominated to take Wallace’s place. On April 12, 1945, just 82 days into his fourth term, Roosevelt died. During that period, Truman had met with the president only twice, and Roosevelt, apparently unaware of how ill he was, made little effort to inform Truman about the administration’s programs and plans, such as the program that would soon produce the atomic bomb.

Truman successfully concluded the war against Germany, brought the United States into the United Nations, and engineered the surrender of Japan through the deployment of the atomic weapon. As his term progressed, however, his popularity diminished, as did that of the Democratic Party, and by the time the 1948 election was on the horizon, he was about the only politician in the United States who thought he had a chance to win election. The Republicans had triumphed in the congressional elections of 1946, running against Truman as the symbol of the New Deal. That electoral victory seemed to indicate that the American people had tired of the Democrats and had grown weary of reform. Some Democrats, believing Truman had no chance, tried to tempt Gen. Dwight D. Eisenhower to seek the Democratic nomination, but he demurred. They also tried to persuade Supreme Court Associate Justice William O. Douglas to run, but he also declined. Still, Truman was confident in his position. In February, at the Jefferson-Jackson day dinner in Washington, D.C., which many Southerners boycotted because of his civil rights program, he declared, “I will tell you who is going to be the next president of the United States. You are looking at him right now!”

The conventions

Dewey supportersEncyclopædia Britannica, Inc.The Republican National Convention met in Philadelphia, June 21–25, 1948. It was a relatively tranquil affair, particularly in comparison with what would take place in Philadelphia the next month at the Democratic convention. The Republican convention, the first ever to be televised, nominated New York Gov. Thomas E. Dewey (also the party’s nominee in 1944) as its presidential candidate and California Gov. Earl Warren as Dewey’s vice presidential running mate. The Republicans adopted a platform that called for the ending of segregation in the military, an equal rights amendment for women to the U.S. Constitution, support for the recognition of Israel (which had declared independence earlier in the year), abolition of the poll tax, and strong enforcement of anticommunist regulations.

The convention was marked by intense conflict, particularly over civil rights. Though a stronger civil rights plank was rejected, the Democratic platform did call for the desegregation of the military, enraging Southerners particularly. (Truman would issue Executive Order 9981 desegregating the military on July 26.) The Mississippi delegation, along with more than a dozen members of the Alabama contingent, left in protest. Still, Truman was nominated on the first ballot, beating Richard B. Russell, a U.S. senator from Georgia, who received the overwhelming backing of the Southern delegates who remained in the hall. The keynote speaker, Alben Barkley, a U.S. senator from Kentucky, was nominated as Truman’s vice presidential running mate without opposition. Particularly notable at the convention was the address by Hubert H. Humphrey, the mayor of Minneapolis, Minn., who made a passionate plea in favour of a stronger civil rights plank and whose city had adopted the country’s first municipal fair employment law, arguing:


Within a few days of the convention’s end, a group of Southerners met in Birmingham, Ala., and formed the States’ Rights Party, popularly labeled the Dixiecrats. The delegates nominated South Carolina Gov. Strom Thurmond as their candidate for president. Worsening Truman’s chances for reelection was also the defection of liberal Democrats, who broke with the president over his hard-line opposition to the Soviet Union. Many of these liberals supported the candidacy of Henry A. Wallace, who ran as the Progressive Party candidate for president.

The campaign

Indeed, the New York Times claimed that Dewey’s election was a “foregone conclusion,” and Life magazine had run a caption several months before the election declaring Dewey the “next president of the United States.” In early September 1948 Elmo Roper, of Roper Research Associates, reported that Truman trailed Dewey by about 13 percent in the polls.

Nevertheless, Truman refused to believe he stood no chance. He launched a cross-country whistle-stop campaign, railing against the “do-nothing, good-for-nothing Republican Congress.”In more than 300 speeches in more than 250 cities and covering some 21,000 miles (34,000 km), Truman hammered away at Republican support for the antilabour Taft-Hartley Act (passed over Truman’s veto) and other conservative policies as crowds responded with “Give ’em hell, Harry!” With three other candidates in the race, Dewey waged a noncommittal campaign, purposely designed to avoid offending any segment of the electorate. The excitement generated by Truman’s vigorous campaigning contrasted sharply with Dewey’s lacklustre speeches.

Election night

Dewey, Thomas E. [Credit: Encyclopædia Britannica, Inc.]Dewey, Thomas E.Encyclopædia Britannica, Inc.As the returns rolled in on election night, Truman took a narrow lead, but political commentators still believed that Dewey would ultimately win. Emblematic of this was the Chicago Daily Tribune’s decision to distribute a paper with the famous headline “Dewey Defeats Truman.” The Tribune was not alone that night in its error. NBC radio commentator H.V. Kaltenborn reported, “Mr. Truman is still ahead, but these are returns from a few cities. When the returns come in from the country the result will show Dewey winning overwhelmingly.” Truman would soon go to bed, convinced that he would win. In the early hours of the morning, Truman was awakened to hear that he led by two million votes but that Kaltenborn was still claiming that Truman would not win. By mid-morning Dewey had sent a telegram to Truman conceding the election. Dewey, clearly dumbfounded, said in a news conference on November 3, “I was just as surprised as you are.”

When the final votes were tallied, Truman had won by a comfortable margin, capturing 49.4 percent of the vote to Dewey’s 45.0 percent. In the electoral college Truman amassed 303 votes by winning 28 states, while Dewey captured 189 electoral votes by winning 16 states. Thurmond drew the votes of only 2.4 percent of the public, though he garnered more than one million votes; because his supporters were concentrated heavily in the South, he was able to win four states (Alabama, Louisiana, Mississippi, and South Carolina) and 39 electoral votes (one Tennessee elector cast his electoral vote for Thurmond rather than Truman, the state’s winner). Wallace won only 13,000 fewer popular votes than Thurmond, but with diffuse support he came close to winning no state.
