As of mid-May 2026, 58 House members have announced they will not seek re-election: 36 Republicans and 22 Democrats. Add in 11 departing senators, and the total congressional exodus reaches 69 lawmakers — the second-highest departure count since 1992. The partisan imbalance is the most telling detail: Republicans are leaving at nearly a 2-to-1 ratio over Democrats.
That ratio matters because it mirrors a pattern. In 2018, 34 House Republicans retired — the previous single-party record — and Democrats went on to gain 40 seats and retake the majority. In 2006, 28 Republicans retired before Democrats picked up 30 seats in the midterms. When members of the president’s party start heading for the exits en masse, it is usually the most reliable leading indicator of a wave election.
Who’s Leaving — and Why
The retirements fall into several categories. Some are generational transitions: longtime leaders like Nancy Pelosi, Steny Hoyer, Jerry Nadler, and Mitch McConnell are passing the torch. Some are driven by redistricting: Texas’ redrawn map alone triggered at least nine departures, as incumbents were drawn into districts with other members or into unfavorable territory.
But the most revealing category is the “fed up” group: members who are leaving because they no longer see a path forward in a Congress they find dysfunctional. The Hill reported that many retiring Republicans cite “legislative gridlock, family commitments, or a wish to make room for the next generation.” One political scientist characterized it as hitting “a kind of wall.”
The most notable retirements include several members who clashed with Trump’s vision of expanded executive power: Sens. Cornyn (if he loses the runoff), Tillis, and Ernst, plus Rep. Don Bacon, whose departure opened NE-02 — now one of Democrats’ top pickup targets.
The Office-Seekers
Not all departures are retirements from politics. Twenty-seven House members are leaving to run for other offices: 16 for the Senate, 11 for governor (10 Republicans and 1 Democrat). This “musical chairs” effect has created open seats in districts that were previously safe for one party but become competitive without an incumbent on the ballot.
The most consequential examples include NE-02 (Bacon retiring, now a toss-up), FL-19 (Byron Donalds running for governor, opening a safe R seat), and GA-01 and GA-10 (Buddy Carter and Mike Collins both running for Senate, opening two seats in a state where Dems are investing heavily).
What It Means for November
Open seats are consistently harder for the departing party to hold. Incumbents win re-election more than 90% of the time; open seats flip at a much higher rate. With 36 Republican-held open seats versus 22 Democratic-held ones, the math structurally favors Democrats — even before accounting for the national environment.
The redistricting wars complicate this picture. Some open Republican seats have been redrawn to be safer (Texas), while some open Democratic seats have become more competitive (Missouri). But on balance, the combination of record retirements and a hostile national environment creates the conditions for a significant Democratic gain in November.
The members who are leaving know this. They are not fleeing a party at the height of its power. They are getting out before the wave hits.
