The 2020 United States Senate election in Montana was held on November 3, 2020, to elect a member of the United States Senate to represent the state of Montana. Republican incumbent Steve Daines won re-election to a second term, defeating Democratic incumbent governor Steve Bullock.
In the June 2 primary elections, Daines and Bullock secured their nominations with minimal opposition.
Originally, this seat was projected to be a safe Republican hold. However, Bullock entered the race on the last day to file, shifting the dynamics of the contest dramatically; many political pundits then considered it a competitive race and a potential pickup for Democrats. One poll showed Bullock leading by seven points. Democrats outspent Republicans $82 million to $63 million on this race; it was one of the most expensive Senate races in the 2020 cycle. On Election Day, Daines prevailed by a relatively comfortable 10% margin following a trend of Republican Senate candidates outperforming expectations.
Despite his loss, Bullock did outperform Biden, who lost Montana by a 16.4% margin. He also flipped two counties won by Donald Trump in the presidential contest — Lewis and Clark and Roosevelt.
This election marked the first time since 2000 where Montana voted for a Republican governor, president, and senator all on the same ballot. As the Green Party was removed from the ballot and both Libertarian nominees withdrew, this was the first time since 1988 that there were no third-party candidates running for either United States House of Representatives or United States Senate in Montana. This was the first time ever that an incumbent Republican senator was re-elected to this seat.
