The 1945 New York City mayoral election took place on November 6, 1945 in New York City. The candidates were King County District Attorney William O'Dwyer, a Democrat, and Jonah J. Goldstein, a Republican judge, as well as other, third party candidates.
O'Dwyer won the contest with 56.77% of the vote.[1]
The American Labor Party nominated O'Dwyer.
The Liberal Party of New York wanted Wendell Willkie to run for mayor and met with him in May 1944. He was interested in the idea, but died in October. The Liberals attempted to negotiate with the Democrats, but O'Dwyer had ties to the ALP. Morris, while running as a Republican, sought the party's support and the Liberals were favorable to Joseph McGoldrick. McGoldrick withdrew from the race and suggested Goldstein, who was approved.
Morris was meant to be on the Republican slate, but he refused the nomination and attacked Goldstein as a "discarded Tammany candidate for mayor". La Guardia asked Morris to run and he announced his candidacy as the nominee of the No Deal Party on August 5.
