Harry S. Truman–Thomas E. Dewey political rivalry

The 1948 presidential contest between Harry S. Truman and Thomas E. Dewey became a contest not only over the presidency but over how a candidate should speak to voters. Dewey entered with the apparent advantage of being the expected winner; Truman, burdened by predictions of defeat, made an energetic, confrontational campaign out of that disadvantage. Their rivalry culminated in Truman’s victory, an outcome that overturned the prevailing forecast but rested on close margins in several decisive states.

The Contest and Its Stakes

Truman’s campaign was his own in its public character: he traveled and spoke with unusual persistence, telling his sister that he had made about 140 stops, spoken 147 times, and shaken hands with at least 30,000 people. He promised that, regardless of the result, voters would know where he stood. Yet the campaign was not simply the work of one candidate. Publicity director Jack Redding later described the campaign as a combination of elements whose effects depended on how they worked together. He and Howard McGrath continued their efforts despite understanding the odds against Truman.

One practical innovation widened the campaign’s reach beyond its English-language audience. Redding enlisted the manager of a Polish-language newspaper in New York to arrange translations of Truman’s press releases for foreign-language newspapers and radio stations. The material appeared in Polish, German, Spanish, Italian, Russian, and Swedish. The book places the effort in a country where roughly 35 million people were foreign-born and 11 million were eligible to vote, making the translation work a substantial part of the campaign’s wider organization.

The candidates’ public approaches diverged most sharply in the closing campaign. In Chicago, Truman addressed a packed stadium of 24,000 and delivered what the account describes as his harshest speech of the campaign, accusing Dewey’s election of threatening democratic government. The speechwriters intended to provoke Dewey into a response, and Truman accepted that strategy. The episode also exposes the strain behind his relentless pace: Clark Clifford later associated the speech’s desperation with the fatigue that had accumulated over the campaign.

Dewey was outraged and drafted a new speech for his own scheduled Chicago appearance. His advisers persuaded him to discard it rather than enter a personal exchange that might make him appear intemperate with victory seemingly close. He instead criticized the Democrats’ campaign attacks and said he would not conduct a campaign of that kind. Truman offered no public explanation or apology in response. He continued east, while Dewey’s train followed a day later. The contrast was consequential: Truman kept pressing his attack, while Dewey’s advisers sought to prevent a risky departure from the composed campaign they wanted him to maintain.

The Result and Its Narrow Margins

The result reversed the expectations that had defined the contest. Truman carried 28 states and received 303 electoral votes; Dewey won 16 states and 189 electoral votes. Truman’s popular-vote total was 24,105,812, compared with 21,970,065 for Dewey, a lead of just over 2.1 million. The result also brought Democratic gains in Congress: the party held 54 Senate seats to the Republicans’ 42, and won the House by 263 seats to 171.

The national totals conceal how vulnerable Truman’s electoral victory was. He carried Ohio by about 7,000 votes, Illinois by 33,000, and California by 17,000. A change in the result in any two of those states would have left him without an Electoral College majority and sent the decision to the House of Representatives. If Dewey had won all three, he would have taken the presidency even though Truman would still have led in the popular vote. The account calculates that a shift of 33,000 votes, distributed across the three states, could have changed the outcome.

The alternative arithmetic also ran in Truman’s favor. Dewey carried New York by only 61,000 votes, while Henry Wallace received about half a million votes there. Clark Clifford later argued that more campaign time in New York might have changed the result. Without Wallace’s vote, or with less support for Strom Thurmond in the South, Truman might have won many more electoral votes. The contest therefore cannot be reduced to a simple story of an inevitable late surge: the decisive map was shaped by narrow state results and by votes cast for candidates other than the two principal rivals.

Why Truman Won—and What the Rivalry Revealed

A Republican Policy Committee study later blamed the loss chiefly on Dewey’s strategy and performance. It faulted his aloofness, speeches pitched above voters’ heads, and acceptance of Democratic claims without adequate challenge. In the committee’s analysis, confidence in the polls had led Dewey to surrender the initiative. The same report judged Truman’s attack on the 80th U.S. Congress politically effective: it shifted the contest away from scrutiny of Truman and his party’s record and toward public dissatisfaction with Congress. The report acknowledged that this tactic was demagogic, even as it credited its effectiveness.

The evidence for Truman’s coalition was broader than a single speech or state. Studies cited in the account identified the farm vote, labor vote, Black vote, and Western vote as important to both Truman’s success and the Democrats’ gains in Congress. Truman won 13 of the country’s largest cities and carried much of the rural Midwest, including Ohio, Illinois, Minnesota, Wisconsin, and Iowa. He also held seven Southern states despite Thurmond’s challenge, won the border states of West Virginia, Kentucky, Oklahoma, and Missouri, and carried every Western state except Oregon. Dewey, meanwhile, won important industrial states in the Northeast, including New York, New Jersey, and Pennsylvania, but those victories were not enough.

The pollsters’ failure to anticipate the result became part of the story of the rivalry. George Gallup and Elmo Roper were publicly astonished. Later studies suggested that the polls had been reasonably accurate until mid-October, but that Gallup’s final survey, released just before election day, was already about two weeks out of date. In those final weeks, many voters who believed Dewey would win nevertheless voted for Truman. The election thus exposed a difference between expectations and choices: public confidence in Dewey’s likely victory did not prevent voters from quietly making another decision at the ballot box.

Truman’s victory made the rivalry a lasting demonstration of the limits of forecasts and the risks of a campaign built on presumed success. Dewey’s composure and apparent advantage could not substitute for electoral engagement, while Truman’s hard-driving appeal helped redirect attention and assemble a winning coalition. But the close results in Ohio, Illinois, and California preserve the contingency of the outcome: the campaign’s reversal was real, and so was the narrowness of the route by which Truman prevailed.
