FairVote's biennial project Monopoly Politics presents an in-depth analysis of elections to the United States House of Representatives and a rigorous critique of the winner-take-all system used to elect it. The project includes our projections for all 435 seats in the 2020 elections, made two years before Election Day, illustrating the lack of competition in these elections.
Our high confidence projections have been over 99% accurate over four election cycles. If we project a seat to be won by a high enough margin in a year in which the voters overall are about evenly divided between the two major parties, then we project the seat with high confidence for the party we expect to win. These projections can only change if a vacancy or retirement occurs, or if a state redistricts. For 2020, we make high confidence projections in 358 seats (82.6% of seats). Our high confidence projections are as follows, and scroll down to see which districts specifically are projected:
Our full projections for all 435 seats depend on two pieces of information about the 2020 elections we cannot predict: how much incumbents are favored and how much the nation leans toward one of the two major parties. Put in those pieces of information to see our projections for all 435 seats.How much will the 2020 elections favor incumbents? Click on the button.

Our winner-take-all system has fundamentally broken elections to the U.S. House of Representatives. An overwhelming majority of voters live in districts locked up for one of the two major parties, and district lines fundamentally decide who wins and who loses, even when far out of step with the will of the voters.
Our high confidence projections have been over 99 percent accurate across four election cycles, including being 100 percent accurate in 2012 and 2016. We have projected more than 80 percent of seats at this highest level of confidence since 2014. Our methodology relies only on prior voting data, without any modifications for campaign finance, public scandals, or opponent quality.

Follow the links below for previous editions of the Monopoly Politics report. While the projection methodology has been refined over the years, it has remained remarkably accurate since its inception.
The projections are based on the innovative "district partisanship" metric introduced in the first Monopoly Politics report in 1997. District partisanship measures the partisan lean of each congressional district by comparing how each major party presidential candidate performed in the district relative to how they performed in the national popular vote.
