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 elections in Arizona and Georgia, Republicans will be defending 23 seats in 2020, while the Democratic Party will be defending 12 seats. Depending on the results of the 2020 presidential election, Democrats will need to pick up either three or four seats to gain a majority in the Senate.[a]

Partisan compositionEdit

As of August 2019 (and including the 2020 special elections in Arizona and Georgia), Republicans are expected to defend 23 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 arise in Class 1 or Class 3 Senate seats.

  • "lean": slight advantage
  • "likely" or "favored": significant, but surmountable, advantage (*highest rating given by Fox News)
  • "safe" or "solid": near-certain chance of victory

NotesEdit

  1. ^ a b 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 Democrats will have to pick up at least four Senate seats to win a majority.
  2. ^ The two independents, Bernie Sanders and Angus King, have both caucused with the Democratic Party since joining the Senate.
  3. ^ Incumbent in 2014, except where noted
  4. ^ a b If no candidate win a majority of the vote in the November 3, 2020 jungle primary, the top two candidates will go to run-off.
