Past Reports

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, with near perfect accuracy in the 75% to 85% of House races that can be projected with high confidence in each election.

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.
