Use this tool to project the partisan result of the 2018 election for all 435 seats in the House of Representatives.

High Confidence Projections

Our high confidence projections have been over 99.9% accurate over three election cycles. If we project a seat to be won by a high enough margin in an even year, 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 2018, we make high confidence projections in 378 seats (86.9% of seats). Our high confidence projections are as follows, and scroll down to see which districts specifically are projected:
