Despite a Democratic majority in the commonwealth, he and running mate Bill Scranton (whose father served as governor in the 1960s) defeated Pittsburgh mayor Pete Flaherty and his running mate, educator Bob Casey (who bears no relation to Robert P. Casey, the 42nd Governor of Pennsylvania). The victory was attributed in part to Thornburgh's campaign promises to crack down on government corruption, at a time when more than 60 persons in the Shapp administration were indicted on criminal charges. Thornburgh and Scranton were reelected in 1982. However, Scranton failed to win the governorship on his own in 1986.
