A nonpartisan election forecaster has adjusted its ratings for 18 House races just weeks before the Nov. 3 election, signaling potential gains for Democrats. The Cook Political Report updated its projections on Oct. 9, estimating that Democrats could flip a net of nine to 19 seats, bringing their total to 224 to 234 seats in the 435-member House. A majority requires 218 seats.
Key shifts in race ratings
The Cook Political Report’s update, authored by Erin Covey, included several notable changes:
- Five races moved from Toss Up to Lean Democrat, including four currently held by Republicans: Rep. Mariannette Miller-Meeks (R-Iowa) vs. Christina Bohannan; Rep. Zach Nunn (R-Iowa) vs. Sarah Trone Garriott; Rep. Ryan Mackenzie (R-Pa.) vs. Bob Brooks; and Rep. Scott Perry (R-Pa.) vs. Janelle Stelson. The fifth is Rep. Marie Gluesenkamp Perez (D-Wash.), whose race has tightened due to progressive opposition over her vote for the SAVE Act.
- Four races shifted from Lean Republican to Toss Up, including seats held by Reps. Bill Huizenga (R-Mich.), Rob Wittman (R-Va.), and an open seat in Iowa’s 2nd District. North Carolina’s 1st District, redrawn by Republicans to challenge Rep. Don Davis (D-N.C.), also moved to Toss Up.
- Three races moved from Likely Republican to Lean Republican, reflecting narrower margins for GOP incumbents.
Forecaster cites ad spending impact
Covey noted that Republicans had anticipated a large ad campaign would weaken Democratic candidates and help GOP incumbents distance themselves from former President Donald Trump. However, the spending “has yet to move the needle” with less than four weeks remaining until Election Day. Democrats now need to win only 20% of the races rated Toss Up to secure a majority, assuming all seats leaning their way break in their favor.
Historical context and competitive districts
The updated ratings reflect tightening races in traditionally competitive districts, particularly in Iowa and Pennsylvania. Three of the four Republican-held seats that shifted to Lean Democrat were won by margins of less than two points in 2024, making them prime targets for Democratic pickup efforts. In Washington’s 3rd District, Rep. Gluesenkamp Perez faces challenges from progressive voters displeased with her SAVE Act vote, though Covey suggested most would still support her over her Republican opponent.
The Cook Political Report’s projections remain a key reference for political analysts tracking the midterm elections, with the latest adjustments indicating a potential shift in the balance of power in the House.
