 Under the City Charter of the day, when O'Dwyer resigned, City Council President Impellitteri became acting mayor.The Tammany bosses did not think he was mayor material, and they refused to nominate him as the Democratic candidate for the special election in November 1950, which instead went to highly regarded New York State Supreme Court Judge Ferdinand Pecora, who was also given the Liberal line.Impellitteri ignored the machine and ran as an independent under the banner of the new "Experience Party".
