US primary elections: Trump-backed candidates lose

The 2026 primary elections delivered mixed results for candidates endorsed by President Donald Trump. In a notable upset, Trump-backed Rep. Randy Feenstra lost the Iowa Republican gubernatorial primary to businessman Zach Lahn, who aligned with the 'Make America Healthy Again' movement. This marked the first defeat of a Trump-endorsed candidate for governor, House, or Senate in the midterm cycle. However, Trump's endorsement proved effective in other races: Rep. Ashley Hinson won the Republican Senate primary in Iowa, and Trump-backed Joe Mitchell secured the House nomination in Iowa's 2nd District. In California, Trump-endorsed Steve Hilton led the crowded gubernatorial primary, positioning himself for the general election alongside Democrat Xavier Becerra. The results highlight the uneven influence of Trump's endorsement as local dynamics and candidate quality played significant roles.

Key Facts

Conclusion

The 2026 primary elections demonstrate that while Donald Trump remains a dominant force in Republican politics, his endorsement is not a guaranteed victory. Voters in Iowa showed they are willing to reject a Trump-backed candidate when faced with a well-funded alternative that resonates on local issues like immigration and health. Meanwhile, Trump's backing continued to be a powerful asset in other races, particularly where candidates had strong local support and clear alignment with his agenda. The mixed outcomes suggest that the Trump endorsement effect is conditional on the specific electoral context, including candidate positioning, spending, and voter priorities beyond national party loyalty.
