as a Representative since 1965, easily received the Republican nomination, and the endorsed Democratic-NPL candidate was Kent Johanneson. Andrews and Johanneson won the primary elections for their respective parties. Two independent candidates, Harley McLain and Don J. Klingensmith also filed before the deadline under the Chemical Farming Banned and Statesman parties respectively. McLain would later run for the same seat in 1998 against then incumbent Byron Dorgan. Ohio Incumbent Democrat John Glenn won re-election to a second term in a landslide with 69% of the vote over Jim Betts, State Representative, coinciding with Ronald Reagan's substantial win in the state during the presidential election. Oklahoma Incumbent Republican Henry Bellmon decided to retire, instead of seeking a third term. Republican nominee Don Nickles won the open seat over Andy Coats, Oklahoma County, Oklahoma district attorney. After two years in the State Senate and displeased by the policies of the Carter Administration, Nickles ran for the United States Senate in 1980 to succeed Republican Henry Bellmon who was retiring. As an unknown in a field crowded with business and political bigwigs, Nickles was not initially given much of a chance. Bellmon even tried to convince him to wait and run for the U.S. House. Utilizing personal contact and passing out unique "wooden nickel" campaign button novelties, Nickles unique grassroot community ties to local Amway distributors throughout Oklahoma gave him an interpersonal network which proved helpful. Nickles beat two well funded oil millionaires (Jack Zink and Ed Noble) in the primary and won the primary run-off against Zink, a race car driver. He later won the general election against Democrat Oklahoma City Mayor Andy Coats and independent Charles Nesbitt, the Oklahoma Corporation Commissioner and former Oklahoma Attorney General. At the age of 32, Nickles was the youngest Republican ever elected to the United States Senate. Oregon Republican incumbent Bob Packwood was re-elected to a third term, defeating Democratic state senator Ted Kulongoski and Libertarian Tonie Nathan. The primary elections were held on May 20, 1980, in conjunction with the Democratic and Republican presidential primaries. Interest in the primaries was somewhat subdued because they occurred just two days after the eruption of Mount St. Helens, about north of Oregon's most populous city, Portland. The eruption (which was a VEI = 5 event) was the first significant one to occur in the contiguous 48 U.S. states since the 1915 eruption of California's Lassen Peak. In
