Why did Harry Truman win in 1948?

Answer 1

Truman ,who was the underdog according to pollsters, ran a great campaign in which he traveled thousands of miles making whistle stops from the back of his rail car. His folksy manner appealed to the rank and file type of people who came out to hear him talk and contrasted sharply with his rich New York Republican opponent.

Answer 2

Truman ran a very effective campaign. He rode around the country by train, making whistles stops to speak to an estimated six-million people. His blunt ,"Give-em Hell" speeches and rural farm background sat well with the rank-and-file voters and contrasted with his somewhat boring and stuffy New York opponent.
