2020 United States House Elections (Santorum in the House)

The 2020 United States House of Representatives Elections were held on November 3, 2020, to elect representatives from all 435 congressional districts across each of the 50 U.S. states, as well as six. Special House elections were also held on various dates throughout 2020. In the 2018 United States House of Representatives Elections, the Republicans had won 243 seats. Leading up to the 2020 elections, the Republicans were projected by many polls to expand their majority by up to 15 seats due to the projected electoral successes of President Richard Santorum. On Election Day, the Republicans significantly outperformed the polling averages, making a net gain of 32 seats. The Republicans entered 2021 with a large 275–160 House majority.

Republicans exceeded expectations in the 2020 House Elections, winning back a number of seats that they lost in 2018, successfully defending competitive seats that Democrats had hoped to flip and unseating additional Democratic incumbents. Only two Republican incumbents were defeated for re-election, while 34 incumbent Democrats were ousted by Republicans. Furthermore, several successful Democratic candidates won by smaller-than-expected margins. Many pundits have cited a combination of Santorum's comfortable re-election victory and the Republican Party's efforts to promote their female and minority candidates as the catalyists of the Republican Party's successes in the House.
