🔥 Trending 2026 US House Incumbent Primary Defeats: Who Lost Their Seats?

In the 2026 U.S. House primary elections, a significant number of incumbents have lost their bids for re-election, marking a volatile election cycle ⁶. As of August 13, 2026, nine House incumbents have lost their primaries ³⁴⁶. This represents the highest number of incumbent primary losses outside of a national redistricting year since 1970 ⁶.

Key Incumbent Losses in 2026 Primaries

While a comprehensive list of all nine incumbents is still developing, some notable losses have been reported:

• Rep. John Larson (D-CT): John Larson, a long-serving Democratic Representative from Connecticut, lost his primary to a non-incumbent. Bronin secured 53.5% of the vote, while Larson received 34.7% ³. This marked the first time since 2014 that an incumbent member of Connecticut's U.S. House delegation faced a contested primary ³.
• Rep. Andy Ogles (R-TN): Republican Representative Andy Ogles of Tennessee became one of the latest House members to lose a primary ⁴.

Context of Incumbent Losses

The high rate of incumbent primary defeats in 2026 is part of a broader trend indicating an unusually volatile election cycle, potentially driven by disillusioned voters ⁶. In addition to the nine House members who lost primaries, another 62 members are not seeking re-election, contributing to a significant shake-up in the chamber ⁴.

Overall, in the 2026 elections, four incumbents—two Democrats and two Republicans—lost re-election in the primary elections for the U.S. House of Representatives ⁵⁷. However, the more recent data indicates the number has risen to nine as of August 2026 ³⁴⁶.

It is important to distinguish primary losses from general election losses. In the general elections, eleven incumbents—four Democrats and seven Republicans—lost their re-election bids ⁵⁷. This further highlights the significant turnover observed in the 2026 election cycle.
