Education and career
Born in Orange, New Jersey, Mahoney received a Bachelor of Arts degree, magna cum laude, from St. Bonaventure University in 1952. He received a Bachelor of Laws from Columbia Law School in 1955 as a Kent Scholar. He was in the United States Coast Guard from 1955 to 1958.

In 1985, Mahoney represented the National Review and its editor, William F. Buckley Jr., during the magazine's $16 million libel suit against The Spotlight.

Conservative Party of New York
Mahoney founded the Conservative Party of New York, with his brother-in-law, Kieran O'Doherty, who served as the new party's first chairman. The Conservative Party was established as a counterweight to the Liberal Party of New York, which endorsed Democrats on the political left. Mahoney authored Actions Speak Louder: The Story of the New York Conservative Party (Arlington House, 1968), which recounts the formation and early years of the party.

Further information regarding Mahoney and the formation of the Conservative Party and its role in the conservative movement through 2002 is available in Fighting the Good Fight, authored by George J. Marlin (St. Augustine's Press, 2002). Marlin was the Conservative Party mayoral nominee in 1993, having been defeated by the then-liberal Republican Rudy Giuliani.
