addition to the candidates chosen in the primaries, Tonie Nathan was chosen as the Libertarian Party candidate at that party's convention in June. Previously, Nathan had been the Libertarian vice presidential candidate in the 1972 Presidential election and was the first woman to ever receive an electoral vote in a U.S. presidential election from a faithless elector who voted for her. As a well-funded incumbent, Packwood was expected to have a fairly easy road to re-election and led by double digit margins in most early polls. Packwood chose defense spending as his key issue in the campaign while Kulongoski focused on the economy and unemployment. Nathan hammered at core Libertarian principles of limited government, with a goal of 5% of votes which would keep the party as a valid minor party. The three candidates agreed to three debates, to be held across the state in the summer of 1980. As the challenger, Kulongoski aggressively attempted to engage Packwood in the debates, but the debate format did not allow the candidates to ask follow-up questions or rebut each other's statements and Packwood was largely able to avoid confrontation and stay above the fray. As the campaign wore on, Kulongoski grew more confident and tried to appeal to Oregonians' independent values by saying that Packwood's enormous cash advantage was due to "eastern" money. Kulongoski closed to within a few points in some late polls, but with no mistakes made by Packwood and with the coattail effect of Ronald Reagan's presidential victory, the incumbent achieved an electoral majority and a fairly comfortable 8-point margin over Kulongoski. Nathan finished with less than 4% of the vote, short of her goal of 5%. With Republicans taking control of the U.S. Senate, Packwood was in line to become chairman of the Senate Commerce Committee. Fellow Oregon Republican senator Mark Hatfield was also elevated to chairman of the Senate Appropriations Committee, giving Oregon power in the Senate it had never seen before. Pennsylvania Incumbent Republican Richard Schweiker decided to retire, instead of seeking a third term. Republican nominee Arlen Specter won the open seat, defeating Democratic nominee Peter F. Flaherty, former Mayor of Pittsburgh. Arlen Specter, formerly a member of the Democratic party, had served as legal counsel to the Warren Commission, which investigated the 1963 assassination of President John F. Kennedy, after which he became District Attorney of Philadelphia. After he was defeated in a 1967
