Heinz easily defeated Vignola to win the election and another term in the Senate, carrying every Pennsylvania county except Philadelphia, Vignola's home town, and by a comfortable 1.49 million vote margin. Heinz performed well in suburban areas, as well as the central, southwestern and northeastern portions of the state. Outside of Philadelphia, Vignola's best county-wide showing was in Mercer County, where he won 36% of the vote, and his poorest county-wide performance was in Snyder County, where he won 12% of the vote. Although Heinz's landslide victory was largely expected among Democratic leaders, Heinz won by a wide margin despite the Democrats' 551,000-voter registration advantage statewide.
