Who Chicago Tribune mistakenly declare winner over President Truman in the 1948 election? Correct
The Chicago Tribune mistakenly declared Thomas Dewey the winner over President Truman in the 1948 election, not Henry A. Wallace, Adlai Stevenson, or Dwight D. Eisenhower. The famous “Dewey Defeats Truman” headline, published by the Chicago Tribune prematurely, became one of the most iconic and embarrassing moments in American journalism history. While Henry A. Wallace, Adlai Stevenson, and Dwight D. Eisenhower were prominent figures in American politics, it was Thomas Dewey who was erroneously declared the victor by the newspaper before the final results were known. President Truman, in a surprising upset, went on to win the election, debunking the premature headline and securing his second term in office.
