Massachusetts Senator Edward M. Kennedy carried only 9 of 67 counties, but still managed a narrow win over incumbent President Jimmy Carter. He won a large majority in Philadelphia and its suburbs, and in the northeast coal regions (See Map below). Kennedy was helped by the Philadelphia City Democratic organization and by Philadelphia Mayor William Green who gave him a last-moment endorsement. Kennedy carried the more traditionally liberal regions of the state, including Philadelphia and the surrounding northeast counties. Carter was successful in the western and central parts of the state, where voters are more moderate and mostly live in rural areas. As he had in 1976, Carter carried the western and rural parts of the state.
