Guerriero served three terms in the Massachusetts House of Representatives and two terms as mayor of Melrose, Massachusetts. In 2002 he received national attention when Governor Jane Swift of Massachusetts invited him to join the Republican ticket as her running mate. Guerriero campaigned as a fighter for lower taxes, fiscal discipline in government, and improved public schools. Governor Swift eventually stepped aside to support fellow Republican Mitt Romney's candidacy, but Guerriero's candidacy made history as the first time an incumbent governor selected an openly gay politician as a running mate.
Guerriero's advocacy for strong local government earned him the 1998 Fenn Award for Political Leadership from the Kennedy Library's New Frontier Society and the Massachusetts Municipal Association. In the words of Governor Swift, Patrick Guerriero is a "person of talent, of integrity, of commitment and class."
