More than 35 House Republicans have announced they will not seek reelection in 2026, compared to roughly 22 Democrats. The total number of House members from both parties not returning to their current seats is 55, the most since record keeping began in 1930, according to Axios. The only year that came close was 1992, when 65 members stepped aside.
The number of Republican retirements alone has already broken the single-party record.
That record was set in 2018, when 34 Republicans did not seek reelection. Democrats picked up 40 seats that November and flipped the House.
Why Members Are Leaving
The Brookings Institution analyzed the wave and found that the average tenure of retiring Republicans has dropped to just five terms. These are not long-serving members coasting to comfortable exits. They are relatively newer lawmakers walking away from a job they have not held long.
Brookings also found that more than half of the retiring Republicans are seeking state and local offices rather than Senate seats or gubernatorial races. That is a meaningful signal. Members who believe Congress is worth fighting for tend to stay or move up. Members who are done with the institution tend to go home.
The Hill reported that the departures reflect “record numbers amid growing dysfunction,” with members citing the toxic partisan atmosphere, the impossibility of getting things done in a chamber this divided, and uncertainty about whether they will still be in the majority after November.
The Historical Pattern
Political analysts have long used retirement numbers as an early indicator of where the midterm environment is heading. Members of Congress have better information than almost anyone about whether their party is going to gain or lose seats. When they choose not to run, it is often because they have done the math.
In 2010, Democrats saw a large wave of retirements before Republicans picked up 63 seats. In 2018, 34 Republicans stepped aside before Democrats picked up 40. The pattern is consistent enough that the party with significantly more retirements is almost always the one that loses ground.
Republicans currently hold a majority so thin that Speaker Mike Johnson can afford exactly one defection on any party-line vote.
Who Is Leaving
The list of departing Republicans includes members from across the conference and the country. Byron Donalds of Florida, John James of Michigan, Sam Graves of Missouri, Ryan Zinke of Montana, Don Bacon of Nebraska, Darrell Issa of California, and Andy Biggs of Arizona are among those who have announced they will not return. Some are running for Senate or governor. Others are simply done.
The open seats they leave behind become competitive in ways that safe incumbencies are not. An open seat in a district Trump won by eight points is a different race than one where a well-funded incumbent is running. Democrats are already building candidate pipelines for these openings.
The Bigger Picture
The retirement wave does not guarantee Democrats take the House in November. Redistricting, candidate quality, turnout, and the national environment all matter. But the departures are a data point that is hard to explain away.
Thirty-five-plus Republicans have looked at the 2026 political landscape and decided they do not want to be part of it. That is not a sign of a party that believes it is about to have a good night.
The 2018 comparison is the one that should keep Republican strategists up at night. That year, the number was 34. Democrats won 40 seats. This year, the number is higher, the majority is thinner, and the political environment for Republicans has not improved.
