Clark sought re-election to another term, but was defeated by Republican nominee Richard Schweiker, member of the U.S. House of Representatives. South Carolina Incumbent Democrat Fritz Hollings easily defeated Republican state senator Marshall Parker in a rematch of the election two years earlier, to win his second (his first full) term. Hollings faced no opposition from South Carolina Democrats, and avoided a primary election. Marshall Parker, the state senator from Oconee County in the Upstate, was persuaded by South Carolina Republicans to enter the race, and he did not face a primary challenge. After a close election loss to Fritz Hollings in 1966, the Republicans felt that Parker might have a chance at defeating Hollings by riding Nixon's coattails in the general election. However, the Republicans did not provide Parker with the financial resources to compete, and he subsequently lost by a bigger margin to Hollings than two years prior. South Dakota Utah Vermont Incumbent Republican George Aiken ran successfully for re-election to another term in the United States Senate; he was unopposed. Washington Wisconsin Incumbent Democrat Gaylord A. Nelson (U.S. senator since 1963) defeated Republican State Senator Jerris Leonard.
