Ralph Caputo, who returned to the State Assembly in 2008 after having served their from 1968 to 1972, is potentially vulnerable because he is an Italian-American from Belleville in a district that has an African-American majority who live in Newark and Irvington. But Caputo has proven himself as an adept campaigner: he won real primaries for Essex County Freeholder in 2002 and 2008, and unseated a Republican Freeholder in '02.
