United States Senate elections, 2020.svg

Incumbent Majority Leader

Mitch McConnell

Elections to the United States Senate will be held on November 3, 2020, with the 33 Class 2 seats of the Senate being contested in regular elections. The winners will be elected to six-year terms extending from January 3, 2021, until January 3, 2027. Additionally, there will be a special election in Arizona to fill the vacancy created by the death of John McCain in 2018.

In 2014, the last regularly scheduled elections for Class 2 Senate seats, the Republicans won a net gain of nine seats from the Democrats and gained a majority in the Senate. Republicans defended that majority in 2016 and 2018, and held 53 Senate seats following the 2018 elections. Democrats held 45 seats after the 2018 elections, while independents caucusing with the Democratic Party held two seats.

Including the special election in Arizona, Republicans will be defending 22 seats in 2020, while the Democratic Party will be defending 12 seats. Because the vice president of the United States has the power to break ties in the Senate, a Senate majority requires either 51 Senate seats without control of the vice presidency or 50 seats with control of the vice presidency. Thus, assuming that the two independents continue to caucus with the Senate Democratic Caucus, the Democrats will have to pick up at least three Senate seats to win a majority. If a Republican is elected as vice president in the 2020 election, then the Democratic Party will have to pick up at least four Senate seats to win a majority.

Partisan composition[edit]

As of November 2018 (and including the 2020 special election in Arizona), Republicans are expected to defend 22 seats in 2020, while the Democratic Party is expected to defend only 12 seats. These figures could change if vacancies or party switches occur. Additional special elections may also be held in 2020 if vacancies should arise in Class 1 or Class 3 Senate seats.
