Moderate Republican Sens. Arlen Specter of Pennsylvania and Bob Packwood of Oregon defeated conservative primary foes. Packwood, who held off a strong challenge by Baptist minister Joe Lutz, will try for a fourth term in November against Rep. Jim Weaver, who won the Democratic primary. Specter, seeking a second term, bested social studies teacher Richard Stokes. Pennsylvania's Democratic Senate battle was won by liberal Rep. Robert Edgar. Oregon Republicans gave their gubernatorial nomination to former Secretary of State Norma Paulus. The Democrats chose Neil Goldschmidt, a former Portland mayor who served as transportation secretary in the Carter Administration.
