Activist, councilwoman, and vice-mayor of Rochester Taking an interest in politics, Costanza volunteered on
W. Averell Harriman's campaign for governor in 1954 and soon became the
Monroe County, New York, executive director of
Robert F. Kennedy's
Senate campaign in 1964. She served as a
Democratic National Committee member from 1972 until 1977. In 1973 she ran for an at-large seat on the Rochester city council, becoming Rochester's first
councilwoman in a
landslide. The recipient of the largest votes traditionally was named mayor, however the council chose a man for the post, naming Costanza vice-mayor, a largely ceremonial position with little power. Costanza caused controversy when she invited fourteen
National Gay Task Force leaders and
gay rights activists to the
White House at the height of
Anita Bryant's
homophobic "Save Our Children" campaign. Constanza did not disclose to some people that she was a lesbian nor dating
Jean O'Leary at the time. The two activists organized this gay activist conference in the White House on March 26, 1977. Costanza went on to arrange discussions between the NGTF co-directors and senior officials of the administration. Public disagreements with some of the president's policies caused controversy and saw Costanza's role in the White House diminished. As her successor
Anne Wexler described it: "OPL under Costanza had functioned as an office providing responsiveness to interest groups, a form of White House case work, but had not taken enough initiative to enlist group support by building coalitions that would move the president’s program on Capitol Hill." Affirming her support for Carter, she resigned from his administration effective September 1, 1978. Following her resignation many feminists were angered with Carter, feeling he had "fired" Costanza, on whom much pressure was put to quit. ==Career and activism after the White House==
