The cook political report is drawing renewed attention as its latest 2026 election ratings track changes across competitive House and Senate contests ahead of the November midterms. The organization’s newest updates include a major round of House rating changes on September 25 and additional Senate shifts earlier in the week.
The Cook Political Report is widely used by political journalists, campaigns, researchers and voters who want a detailed view of election competitiveness. Rather than simply reporting polling numbers, its analysts evaluate the political environment, candidates, district or state characteristics and campaign developments when assigning race ratings.
With the 2026 midterms approaching, its ratings have become especially relevant because relatively small changes in a limited number of competitive races can affect the broader picture of congressional contests.
What Is the Cook Political Report?
The Cook Political Report is an independent, nonpartisan political analysis organization focused on U.S. elections and campaigns. Charlie Cook founded the publication in 1984 after working in politics and polling. It originally operated as a newsletter and later developed into a digital political analysis platform.
The organization covers several major areas of American elections, including:
- U.S. House races
- U.S. Senate races
- Governor races
- Presidential elections
- National political trends
- Congressional district political data
- Campaign advertising and battleground issues
Its race ratings are among its most recognizable features. The ratings use a seven-category scale that ranges from Solid Democratic to Solid Republican, with Toss Up in the middle.
The ratings are designed to measure competitiveness, not to declare election results before voters cast their ballots.
How Cook Political Report Race Ratings Work
The organization currently evaluates races using seven classifications:
| Rating | General meaning |
|---|---|
| Solid Democratic | Not considered competitive |
| Likely Democratic | Democratic advantage, but some potential for increased competition |
| Lean Democratic | Competitive race with a Democratic advantage |
| Toss Up | Highly competitive contest |
| Lean Republican | Competitive race with a Republican advantage |
| Likely Republican | Republican advantage, with some potential for increased competition |
| Solid Republican | Not considered competitive |
Cook says its ratings consider factors including the political makeup of a district or state, candidate strengths and weaknesses, the political environment and information gathered from candidates and campaign professionals.
That approach makes the ratings different from a simple poll average. A poll measures voter preferences at a particular moment. A race rating incorporates a broader assessment of the contest.
The organization also updates its ratings throughout the election cycle. As campaigns develop, candidates change, advertising increases and new polling becomes available, a race can move from one category to another.
Latest Cook Political Report House Ratings
The latest House ratings were updated September 25, 2026. The current Cook ratings divide all 435 House races into seven categories.
The current breakdown is:
- 185 Solid Democratic
- 12 Likely Democratic
- 11 Lean Democratic
- 22 Toss Up
- 10 Lean Republican
- 19 Likely Republican
- 176 Solid Republican
That produces 218 races rated Solid for either party, while 62 additional contests fall into the Likely or Lean categories. Another 22 races are currently classified as Toss Ups.
The September 25 update attracted particular attention because 15 House race ratings moved toward Democrats. The changes included two Republican-held districts moving from Toss Up to Lean Democratic and several Republican-held contests moving into more competitive categories.
Arizona’s 1st Congressional District and New Jersey’s 7th were among the Republican-held districts moved from Toss Up to Lean Democratic. Texas’ 15th District, represented by Republican Rep. Monica De La Cruz, moved into the Toss Up category.
The Cook ratings page also lists 22 current House Toss Ups, including contests in Arizona, California, Colorado, Florida, Iowa, Michigan, New York, Ohio, Pennsylvania, Texas, Virginia and Wisconsin.
Why the September House Update Matters
The September 25 changes show how quickly the Cook ratings can respond to new campaign information.
The organization said new polling and advertising spending supported the 15 rating changes. Its current House board places 208 races in the Solid, Likely or Lean Democratic categories and 205 in the corresponding Republican categories, leaving 22 contests in the Toss Up column.
Those figures should not be treated as election results.
They represent the current classification of individual contests. The ratings can change again before Election Day, and Toss Up races remain especially sensitive to later developments.
The distinction is important for anyone searching for the latest Cook Political Report information. A race rating is a snapshot of competitiveness rather than a vote count.
Latest Senate Ratings
The Senate picture received a significant update on September 23, 2026.
The latest Senate rating board contains 34 Democratic-held seats not up for reelection and 31 Republican-held seats not up for reelection. Among the seats being contested, Cook’s ratings include seven Toss Ups.
The current categories shown on the September 23 Senate ratings are:
- 9 Solid Democratic
- 2 Likely Democratic
- 1 Lean Democratic
- 7 Toss Up
- 1 Lean Republican
- 2 Likely Republican
- 13 Solid Republican
The September update also changed three races in a Democratic direction. Georgia moved from Lean Democratic to Likely Democratic, Kansas moved from Likely Republican to Lean Republican, and South Carolina moved from Solid Republican to Likely Republican.
Cook’s Senate editor Jessica Taylor described control of the chamber as a “true toss up” in the September 23 analysis, emphasizing that several closely contested races remain central to the Senate landscape.
For readers following Senate races, the ratings provide a way to distinguish contests that remain relatively settled from those receiving intense campaign attention.
Cook Political Report and the Governor Races
The organization also tracks gubernatorial elections.
Its ratings system for governors follows the same seven-category structure used for congressional contests. The September 18 governor summary listed 24 Democratic-held or Democratic-rated seats and 26 Republican-held or Republican-rated seats in its broader state-of-play summary.
Governor ratings can also change as campaigns develop.
One recent example is Alaska. Cook shifted the state’s gubernatorial race to Toss Up in September after previously rating it toward the Republican side. The change followed new polling and developments in the four-way contest.
The organization also moved the Oregon governor race toward Republicans during September while shifting Alaska in the opposite direction.
These updates demonstrate why checking the latest rating date matters. A rating from several months earlier may no longer describe the current state of a contest.
The Cook Partisan Voting Index
Another important feature connected to the Cook Political Report is the Cook Partisan Voting Index, commonly called the Cook PVI.
The PVI measures how a state or congressional district has performed at the presidential level compared with the nation as a whole. It provides a way to understand the underlying partisan character of a district before considering the individual candidates in a particular election.
The PVI is different from a race rating.
A district can have a strong partisan lean while still becoming competitive because of candidate quality, national political conditions or unusual campaign circumstances. Conversely, a district with a relatively modest partisan advantage can remain difficult for the opposing party to capture.
Cook says the PVI was developed in 1997 and has become a commonly used measure of congressional and state partisanship.
Who Runs the Cook Political Report Today?
Charlie Cook founded the organization and led it for decades. In August 2021, Amy Walter became owner, publisher and editor-in-chief. The publication subsequently became known as The Cook Political Report with Amy Walter.
The current team includes analysts covering different parts of the electoral landscape.
Erin Covey leads House race analysis, while Jessica Taylor oversees Senate and gubernatorial analysis. Amy Walter leads national political analysis, with David Wasserman and Carrie Dann also contributing to the organization’s broader election coverage.
The team structure allows the organization to maintain separate expertise for congressional, gubernatorial and national political coverage.
Why People Follow Cook Political Report Ratings
The main attraction is the combination of race-by-race analysis and regularly updated ratings.
Instead of treating every election contest equally, the system identifies which races are considered settled, which deserve monitoring and which are sufficiently competitive to receive a Toss Up designation.
The organization says it has rated more than 11,000 elections since 1984. Its own historical review of ratings from 1984 through 2022 found that Lean ratings were correct 95.3% of the time, Likely ratings 97.4% and Solid ratings 99.9%.
Those historical figures describe past rating performance. They do not guarantee the outcome of any current 2026 race.
That distinction is particularly important during an election year, when ratings can change repeatedly.
What the Latest Updates Show
As of September 28, 2026, the Cook Political Report’s most recent public updates show an active and changing 2026 electoral landscape.
The House board was updated September 25, while the Senate ratings were updated September 23. The latest House update moved 15 contests toward Democrats, while the latest Senate update moved three races toward Democrats.
At the same time, the Cook Political Report continues to maintain a broad range of ratings rather than placing every competitive contest on the same side.
That makes the individual race pages important. The overall numbers provide context, while the race-by-race ratings show where the organization sees the greatest level of competition.
For readers tracking the 2026 midterms, the latest rating date is therefore just as important as the rating itself.
What Readers Should Know About Cook Ratings
Cook ratings are analytical assessments, not official election results.
They can change before Election Day as new polling appears, candidates change their campaigns, advertising shifts and political conditions develop. The organization explicitly describes its ratings as assessments of competitiveness.
Readers should also distinguish between a Toss Up designation and a prediction of a specific winner. A Toss Up means the race is considered highly competitive, while Lean and Likely ratings indicate varying degrees of advantage.
The ratings are most useful when read alongside the underlying race information.
As the 2026 midterms enter their final weeks, the Cook Political Report remains a closely followed source for tracking those changes across House, Senate and governor contests.
Final Takeaway
The latest Cook Political Report updates provide a current snapshot of the 2026 election landscape, with the House and Senate ratings showing numerous competitive contests and several recent rating changes.
