With strong support from organized labor, Hubert Humphrey won Pennsylvania's primary, his first victory in the 1972 Democratic primaries. Organized labor helped Humphrey win the mining and milling town areas of western Pennsylvania; he won every county west of the Susquehanna River, except for Centre and Union (See Map below). Humphrey's victory was geographically broad based. With the exception of the southeastern counties that surrounded Philadelphia and the northeast, he won every region of the state. Philadelphia's suburban counties went for McGovern. Humphrey won 481,900 popular votes, or 35% of the total. Wallace won 292,137, or 21% of the vote; McGovern won 280,861, or 20% of the vote; Muskie won 279,983, or 20% of the vote; Henry Jackson won 38,767, or 3%.
