The only man who could strut sitting down was the crack that made the rounds. But on Nov. 2, Election Day, an overwhelming sense of inevitability hung about the Republican nominee. The polls and the pundits left no room for doubt: Dewey was going to defeat President Harry S. Truman.

President Harry S. Truman holds up a copy of the Tribune after his presidential election, arguably one of the most famous headline mistakes. As a presidential candidate, Gov. Thomas Dewey of New York was not a glad-hander, not a flesh-presser. He was stiff and tended toward pomposity.

On November 3, 1948, the day after the U.S. presidential election, the front-page headline of the Chicago Tribune proclaimed: “Dewey Defeats Truman.” In fact, the newspaper got the story all wrong, because President Harry Truman ended up scoring a surprise victory over his opponent, Governor Thomas Dewey of New York.

Truman ran more against the 80th Do Nothing Congress than he did against Dewey. He made a strenuous campaign that covered almost 22,000 miles and almost 300 speeches. He called the 80th Congress the worst in history which had stuck a pitchfork in the farmer's back..

In the 1948 presidential election, there was no Roosevelt, but a field of the two major candidates, as well as Dixiecrat Strom Thurmond and Progressive Party candidate Henry Wallace. The polls predicted a Dewey victory of between 5 to 15 percentage points, but Truman won by 4.4 percentage points. The labor vote was energized as Democrats worried about Dewey's strength in preelection polls, and Republicans felt their candidate would win so they played golf that day, Roper said.

WASHINGTON — Political pollsters quite accurately boast of the reliability of their science, but polling's biggest ever goof remains alive 50 years later in a headline seared into America's collective memory: Dewey Defeats Truman..

Truman vs. Dewey. Probably the biggest surprise in the history of presidential elections, Harry Truman defied the odds in winning re-election in 1948. When the campaign started, no one except Truman himself expected he would win. In the 1946 elections, the Republicans had captured both houses of Congress.

Heading into Election Day on November 2, 1948, numerous polls and pundits predicted Thomas Dewey (1902-71) was a shoo-in for the presidency. A Michigan native and attorney who gained prominence in the 1930s by prosecuting such mobsters as Lucky Luciano, Dewey had served as the 47th governor of New York since 1943.
