2020 United States Senate election in Oklahoma
From Wikipedia, the free encyclopedia
The 2020 United States Senate election in Oklahoma was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Oklahoma, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives, and various state and local elections. Incumbent Republican Senator Jim Inhofe won reelection to a fifth full term, defeating Democratic challenger Abby Broyles.[1]

This proved to be the fifth U.S. Senate election in Oklahoma in a row in which the Democratic nominee failed to carry any of Oklahoma's counties, but Broyles came very close to breaking this drought, losing Oklahoma County by less than one percentage point. To date, this election has seen the largest age-gap between major party nominees in a U.S. Senate election, as Inhofe was nearly 55 years older than Broyles.
