2020 United States presidential election in Oklahoma

The 2020 United States presidential election in Oklahoma was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Oklahoma voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Oklahoma has seven electoral votes in the Electoral College. Trump easily carried Oklahoma on Election Day by a margin of 33 %, down from 36 points in 2016. Oklahoma was one of two states where Trump won every county (though Oklahoma County was won by a plurality of votes, compared to the absolute majorities achieved across the state), the other being West Virginia. This also signaled the fifth consecutive election in which the Republican candidate carried every county in the state, including those counties encompassed by Native American reservations. In this election, Trump also became the first presidential candidate ever to win more than a million votes in Oklahoma. Biden, however, came within 3,326 votes of winning Oklahoma's most populous county Oklahoma County, and won more than 40% of the vote in Oklahoma's second-most populous county Tulsa. No Democratic presidential candidate has won Oklahoma County since Lyndon B. Johnson in his 1964 landslide, or Tulsa County since Franklin D. Roosevelt in his 1936 landslide. This is the first election since 2000 in which not every county voted in the majority for the Republican, as Oklahoma County was won by Republicans with a 49 % plurality. However, these gains in urban Oklahoma were partly offset by continued falloff in southeast Oklahoma, where Biden even underperformed Hillary Clinton's performance four years earlier in most counties.
