Caputo was elected to the
New York State Assembly in 1972, representing a district in Yonkers. The Republican state convention nominated them in the fall of 1978. D'Amato defeated Javits in the Republican primary and won the general election in the fall. In his autobiography, "Power, Politics, and Pasta: The World According to Senator Al D'Amato" (1995), D'Amato bitterly criticized Caputo. In 1981, President Reagan nominated Caputo as an alternate United States delegate to the United Nations General Assembly. The Senate confirmed the nomination and Caputo began serving in the spring of that year. Early in 1982, Caputo announced his candidacy for U.S. Senate against incumbent Democrat
Daniel Patrick Moynihan, who was seeking a second term. Though he was considered a rising star in the Republican Party, and he raised money from around the country, Caputo ended his campaign after failing to get the support of key Republican and Conservative Party county leaders. After leaving politics, Caputo worked as a lawyer and private investor in real estate and early stage privately held companies. ==Personal life==
