BY DANIELA ALTIMARI Originally seen on Hartford Courant Republican David X. Sullivan, a former federal prosecutor from New Fairfield, is launching his campaign to unseat U.S. Rep. Jahana Hayes, a Democratic freshman from Wolcott. Sullivan will make his kick off announcement at a press conference Saturday in Southbury. Sullivan, 60, says he’s “a career prosecutor, not a career politician.” He retired from the U.S. Attorney’s office on June 28 and filed his paperwork to run for Congress on July 1. Sullivan said he decided to get into the race because he does not believe one-party rule is good for Connecticut. Every member of the state’s congressional delegation, including its two U.S. senators, are Democrats. “We need diversity of thought and diversity of representation,” Sullivan said. Sullivan is the married father of five children, ranging in age from 28 to 7. He graduated from The Catholic University of America and has taught law and other subjects at Yale, Quinnipiac and the University of New Haven.
