The Cook Political Report updated its ratings for 14 U.S. House and Senate races on October 30, 2026, shifting the majority of adjustments in favor of Democratic candidates just days before the November 3 midterm elections.
Two key developments emerged from the update: First, the forecaster projected Democrats could flip 12 to 25 House seats, potentially securing up to 240 seats—their largest majority since 2009. Second, the report reclassified 12 House races as more competitive, with 8 Republican-held seats moving toward Democrats and 3 Democratic-held seats seeing heightened Republican competition.
Immediate Impact on Key Races
The adjustments included Ohio’s 9th District, where Democratic Rep. Marcy Kaptur’s seat shifted from Toss-Up to Lean Democratic despite redistricting efforts favoring Republicans. In Pennsylvania’s 1st District, Republican Rep. Brian Fitzpatrick’s seat moved from Lean Republican to Toss-Up, while Indiana’s 5th District, held by Republican Rep. Victoria Spartz, shifted from Likely Republican to Lean Republican. Florida’s 9th District, represented by Democratic Rep. Darren Soto, also moved from Likely Republican to Lean Republican after redistricting, despite Trump’s 2024 margin of 18 points in the district.
Senate and Gubernatorial Adjustments
Beyond House races, the Cook Political Report adjusted Senate and gubernatorial contests. In the Senate, Florida moved from Solid Republican to Likely Republican, while Nebraska shifted from Likely Republican to Lean Republican. For governor races, Wisconsin moved from Toss-Up to Lean Democratic, and Arizona shifted from Lean Democratic to Likely Democratic.
Historical Context and Forecasting Methodology
The Cook Political Report, described as a nonpartisan election forecaster, has updated its ratings multiple times in the final weeks of the campaign. Previous shifts on October 23 included 19 races moving toward Democrats, with 4 Republican-held seats reclassified. The latest adjustments reflect increased competitiveness in districts where polling, fundraising, or redistricting has altered traditional partisan advantages.
Funding and Strategic Responses
The House Majority PAC, a Democratic super PAC, allocated $380,000 in television ads opposing Rep. Spartz in Indiana’s 5th District, signaling the party’s focus on flipping the seat. Meanwhile, Republicans have countered with significant spending, including $500,000 by Rep. Richard Hudson, chairman of the National Republican Congressional Committee (NRCC), in North Carolina’s 9th District.
Redistricting and Polling Influences
Several races were affected by redistricting, which altered district boundaries to favor one party over another. For example, Ohio’s 9th District was redrawn in October 2025 to favor Republicans, yet the Cook Political Report shifted the race toward Democrats. Similarly, Florida’s 9th District underwent redistricting in May 2026, though polling showed a tied race between Soto and Republican challenger Dan Green.
What’s Next
Voters will decide the balance of power in Congress on November 3, with the Cook Political Report’s latest projections suggesting Democrats hold a slight edge in the House and a competitive landscape in the Senate. The forecaster emphasized that Democrats could secure their majority if they win all 18 Toss-Up races currently rated in their favor.
