John Haggerty, Jr., is a member of a powerful Queens political family, whose patriarch, John Haggerty Sr., was chief counsel and adviser to a former Senate majority leader, Warren Anderson of Binghamton, and was an influential leader of the Queens Republican Party. Mr. Haggerty, Sr.'s sons, John Jr. and Bart, are longtime activists in Queens Republican politics. The brothers founded the Forest Park Republican Club, an unofficial GOP organization in Forest Hills that endorsed the mayor last month, and have been described by party leaders as "insurgents," who have consistently opposed the borough's Republican establishment. The younger John Haggerty, Jr., -- until March a legislative aide to Governor Pataki -- was also a 2005 deputy campaign manager for Mayor Michael Bloomberg, responsible for shoring up Republican support for the mayor in Queens.
