2018 United States House of Representatives election ratings

Last updated March 06, 2024

The 2018 United States House of Representatives elections were held on November 6, 2018, with early voting taking place in some states in the weeks preceding that date. Voters chose representatives from all 435 congressional districts across each of the 50 U.S. states. Non-voting delegates from the District of Columbia and four of the five inhabited U.S. territories ^{[lower-alpha 1]} were also elected. These midterm elections took place nearly halfway through the first term of Republican President Donald Trump. The winners will serve in the 116th United States Congress, with seats apportioned among the states based on the 2010 United States census. On Election Day, Republicans had held a House majority since January 2011 as a result of the 2010 elections.

In the 2018 midterm elections, the Democrats won control of the House and had a net gain of more than 40 seats from their total after the 2016 elections (including one seat gained previously with Conor Lamb's March 2018 special election victory). This was their largest gain of seats since the 1974 elections, when they picked up 49 seats.

Election ratings

Latest published ratings for competitive seats

Several sites and individuals publish ratings of competitive seats. The seats listed below were considered competitive (not "safe" or "solid") by at least one of the rating groups. These ratings are based upon factors such as the strength of the incumbent (if the incumbent is running for re-election), the strength of the candidates, and the partisan history of the district (the Cook Partisan Voting Index is one example of this metric). Each rating describes the likelihood of a given outcome in the election.

Most election ratings use:

Tossup: no advantage
Tilt (sometimes used): very slight advantage
Lean: significant, but not overwhelming advantage
Likely: strong, but not certain advantage
Safe or Solid: outcome is nearly certain

The following are the latest published ratings for competitive seats.
