Sen. Joni Ernst expected not to seek reelection in 2026

 August 30, 2025

In a move that could shift the political landscape in Iowa and the broader Republican Party, U.S. Senator Joni Ernst is reportedly planning to announce that she will not seek reelection for a third term in 2026.

According to Military, the potential departure of Ernst adds to a growing list of Republican senators not seeking reelection, presenting opportunities for the Democratic Party.

Joni Ernst, the first woman from Iowa elected to the U.S. Congress and a veteran of the Iraq conflict, was confirmed by multiple sources to be making her official announcement come September. The news, initially reported by CBS News, highlights the possibility of a significant vacancy in Iowa, a state noted for its political swings.

Ernst’s Legacy in Iowa Politics

Ernst's political career began with her election to the Senate in 2014, and she quickly rose to prominence, holding leadership roles within the Senate GOP. Her influence extended to national politics, where she was considered a potential vice-presidential running mate during Donald Trump's first presidential campaign.

This decision mirrors an earlier development when Iowa’s Governor Kim Reynolds opted against pursuing re-election, prompting other Republicans in the state to evaluate their political strategies moving forward. Iowa, despite its more recent tilt towards the Republican Party, remains a key interest for Democrats looking to regain lost ground.

Historically seen as a swing state, Iowa has more recently trended Republican since Republicans won significant governmental positions, such as the governorship and multiple Senate seats, dating back to 2010 and 2014, respectively. Ernst’s decision not to run again opens the door for several Republican and Democratic hopefuls eyeing Iowa as a critical battleground.

Potential Republican and Democratic Candidates

The potential election scenario following Ernst’s departure is already drawing the attention of key political figures. Representative Ashley Hinson is among those named as a possible contender for the vacated Senate seat.

The competitive nature of the forthcoming election cycle is highlighted by at least two Republican figures and four Democrats expressing interest in vying for the seat. This shapes Iowa as a potentially fierce electoral landscape amidst the upcoming midterms.

Joni Ernst's political journey has been marked by both support and criticism. She faced backlash concerning statements about Medicaid cuts during a public meeting and took a cautious stance against Trump’s nomination of Pete Hegseth for Secretary of Defense, citing Hegseth's previous comments and misconduct allegations.

Political Challenges and Future Opportunities

The political climate in Iowa has been increasingly complex, with registered Republican voters seeing an uptick—undoubtedly benefiting Ernst’s previous campaigns. However, the dynamic nature of the state’s political tendencies continuously offers a vibrant environment for competition between the two major parties.

In 2022, Ernst also faced criticism from within her own party for her decision to protect same-sex marriage, making her a distinctive figure in the broader Republican spectrum. As discussed by Iowa Republican strategist Luke Martz, Ernst's announcement adds to what could be a tumultuous midterm election.

Martz commented on the upcoming challenges, stating, "We’re going into what could be a tumultuous midterm, with two seats already highly targeted. This would be a third, depending on who we nominate."

The Future of Iowa's Political Landscape

The anticipation surrounding Ernst’s official announcement, coupled with other developments such as Governor Reynolds’s reelection decision, distinguishes Iowa as an exciting area to watch in the national political arena.

The engagement from both Republican and Democratic parties underscores the significance of Iowa's influence in upcoming elections. The focus on Iowa as a pivotal battleground unites and also divides, reflecting broader national trends.

As Iowa steers towards its upcoming electoral season, both parties will likely intensify their efforts to capitalize on any shifts in voter sentiment, a process expected to redefine political alignments and ambitions in the Hawkeye State.
