71 new members of Congress elected in 2020 election

Seventy-one new members were elected to the 117th U.S. Congress on Nov. 3, 2020, or in subsequent runoff elections: nine new senators and 62 new representatives. This includes Rep.-elect Luke Letlow (R-La.), who died from complications related to COVID-19 on Dec. 29.

The last race was called on Feb. 8, when the New York Board of Elections voted to certify the results of New York’s 22nd Congressional District election after months of legal challenges.

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.

All 435 U.S. House seats and 35 of the 100 U.S. Senate seats were up for election in 2020. 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.
