Seventy-one new members won election to the 117th Congress on November 3, 2020, or in subsequent runoff elections: nine to the Senate and 62 to the House.[1]

All 435 U.S. House seats and 35 of the 100 U.S. Senate seats were up for election. Five senators — one Democrat and four Republicans — were defeated by candidates of the opposing party. Thirteen members of the U.S. House, all Democrats, were defeated by Republican challengers. In 53 of the 470 seats up for election — four in the Senate and 49 in the House — a non-incumbent was guaranteed to be elected. Republicans held 38 of those seats, Democrats held 14, and a Libertarian held one.

In the Senate, the four open seats were held by three retiring Republicans and one retiring Democrat.

In the House, the 49 open seats were held by 35 Republicans, 13 Democrats, and one Libertarian. Thirty-six seats were open because the incumbent did not seek re-election. This included 26 Republicans, nine Democrats, and one Libertarian. Eight seats — held by five Republicans and three Democrats — were open because the incumbent was defeated in a primary or convention. Five seats were vacant, including the one Democratic seat left open by Rep. John Lewis’ (D-Ga.) death and four Republican seats left open by resignations and appointments.

Five of those open House seats switched party control. Democratic candidates won three Republican-held open seats, and Republicans won one Democratic-held and one Libertarian-held open seat.

In 2018, 102 new members won election to the 116th Congress: nine senators and 93 representatives. Seven new senators and 55 new representatives won election to the 115th Congress in 2016 for a total of 62 new members.
