Ten incumbent House lawmakers have already lost their primaries in the 2026 election season, a sharp early cull that has knocked out three Republicans and seven Democrats. Among the biggest names to fall are Dan Crenshaw, Thomas Massie and Andy Ogles, all of them defeated while seeking another term.
That total gives readers a running count of how rough this primary season has become for sitting members. Crenshaw, who has served in the House since 2019, lost the GOP primary for Texas' 2nd Congressional District to state Rep. Steve Toth. Massie, in the U.S. House of Representatives since late 2012, lost the Republican primary for Kentucky's 4th Congressional District to Ed Gallrein. Andy Ogles, who has served since 2023, lost the GOP primary for Tennessee's 5th Congressional District to Charlie Hatcher.
The defeated incumbents also include Al Green and Julie Johnson in Texas, Dan Goldman and Adriano Espaillat in New York, Diana DeGette in Colorado, Shri Thanedar in Michigan and John Larson in Connecticut. That mix leaves the losses split cleanly between Republicans and Democrats, with the Democratic side accounting for most of the names that have surfaced so far.
Crenshaw's loss lands in a state where the failed Texas and Tennessee incumbents were dealing with redistricting changes that applied to this cycle. Massie's race carried its own weight as well: reports indicate it became the most expensive U.S. House primary contest ever. In Ogles' case, the upset was harder to miss because he had Donald Trump's endorsement, while Trump did not endorse either man before the Crenshaw race and has since backed Toth.
What happens next is straightforward and unforgiving. These incumbents are out of the race, and the number to watch now is whether the total of 10 holds as the season goes on or climbs higher, because the primary map has already shown that seniority is no shield.
