Halfway Through 2026 Primary Season: Six Key Takeaways from Congressional Races

Four more states held primaries this week, bringing the total to 26 states that have completed regular congressional primaries in the 2026 midterm cycle. Key patterns emerging include front-runners not always winning, House members struggling to advance to statewide office, and President Trump's endorsement record remaining largely successful despite low approval ratings. These trends are shaping the competitive landscape for the general election.
With 26 states having completed regular congressional primaries as of this week—including Maine, Nevada, North Dakota, and South Carolina—the 2026 midterm primary season is at its halfway point. Several important runoffs remain scheduled across multiple states through late July. The analysis identifies six significant patterns: while some front-runners like Rep. Ashley Hinson and former Gov. Roy Cooper won decisively, others like Xavier Becerra and Josh Turek came from behind to secure nominations. House members attempting to move to statewide office have faced particular difficulty, with multiple representatives finishing poorly in gubernatorial and Senate races. Meanwhile, President Trump's endorsement continues to carry substantial weight in Republican primaries, with his endorsed candidates winning most races, though there have been exceptions. These dynamics suggest competitive general elections ahead in several key races.

The conflict came to a head when the DOJ and FBI released a memo concluding there was no evidence of an Epstein client list, which Bongino viewed as misaligned with transparency promises.
