1978 United States Senate election in Montana
The 1978 United States Senate election in Montana took place on November 7, 1978. Following the death of United States Senator Lee Metcalf on January 12, 1978, Montana Supreme Court Chief Justice Paul G. Hatfield was appointed to serve for the remainder of Metcalf's term. Hatfield opted to run for re-election, but was overwhelmingly defeated in the Democratic primary by United States Congressman Max Baucus of the 1st congressional district. Baucus advanced to the general election, where he was opposed by Larry R. Williams, an author and the Republican nominee. Baucus ended up defeating Williams by a solid margin to win his first term in the Senate, and, following Hatfield's resignation on December 12, 1978, he began serving his first term in the Senate.
Mike Cooney
Cooney continued working for Baucus until 1988, when he was encouraged to run for Secretary of State of Montana. An old friend of his sent a $100 campaign donation after hearing Cooney defend Baucus' vote for the Gramm–Rudman–Hollings Balanced Budget Act of 1985 and Cooney decided to run. He received permission from Baucus to run, though reluctantly, as Baucus did not want to lose him, so Cooney agreed to only campaign on evenings and weekends. Cooney was unopposed in the Democratic primary and defeated the Republican nominee, State Senator Pete Story, by 174,917 votes (49.28%) to 163,830 (46.16%). His victory was considered an upset as he was outspent by his opponent and Republicans had won the open gubernatorial seat, incumbent Democratic U.S. Senator John Melcher was defeated by Republican Conrad Burns and George H. W. Bush carried the state's four electoral votes in the presidential election. Along with Montana Superintendent of Public Instruction Nancy Keenan and Clerk of the Montana Supreme Court Ed Smith, Cooney was one of only three Democrats to win a statewide election in Montana that year.
