Early life and career

Joni Kay Culver was born on July 1, 1970, in Montgomery County, Iowa, to parents Marilyn and Richard Culver. She completed her high school education at Stanton Community School District High School, where she graduated as valedictorian. Following high school, Ernst pursued higher education at Iowa State University, earning a Bachelor of Arts degree in psychology in 1992. She furthered her education by obtaining a Master of Public Administration degree from Columbus State University in 1995. During her time in college, she participated in an agricultural exchange program that took her to the Soviet Union, which provided her with a broader perspective on international relations and agriculture.

Ernst's military career began when she joined the Reserve Officers' Training Corps (ROTC) program at Iowa State University at the age of 20. After completing her education, she entered the United States Army Reserve. Over the course of her military service, she rose to the rank of lieutenant colonel in the Iowa Army National Guard. Ernst's military experience included a deployment to Kuwait during the Iraq War, where she served as the commanding officer of the 1168th Transportation Company. She later commanded the 185th Combat Sustainment Support Battalion at Camp Dodge, which is recognized as the largest battalion in the Iowa Army National Guard. Ernst's military career spanned 23 years, culminating in her retirement in 2015. Throughout her service, she received several awards, including the Meritorious Service Medal and the Global War on Terrorism Expeditionary Medal.

In addition to her military service, Ernst began her political career in local government. She was elected as the auditor of Montgomery County in 2004, defeating the incumbent. She ran unopposed in 2008 and was reelected, securing 4,569 votes. Ernst transitioned to state politics when she won a special election for the Iowa State Senate in 2011, representing District 12 in southwestern Iowa. She was subsequently reelected in 2012. After being elected to the U.S. Senate in 2014, Ernst resigned from her position in the Iowa State Senate effective November 28, 2014.

Senate tenure

Joni Ernst announced her candidacy for the U.S. Senate in July 2013, seeking to fill the seat vacated by retiring Democratic Senator Tom Harkin. Her campaign gained momentum with endorsements from prominent figures, including Iowa Lieutenant Governor Kim Reynolds and former governors Mitt Romney and Sarah Palin. Ernst's campaign was significantly supported by the Koch brothers, who contributed substantial financial resources to her efforts, including television advertisements and direct campaign contributions.

One of the notable moments of her campaign was a widely circulated advertisement in which she humorously compared her experience in castrating pigs to her ability to "cut pork" in Congress. This advertisement garnered significant media attention and helped elevate her profile within the Republican primary, allowing her to emerge as a strong contender. Despite facing criticism regarding her attendance and voting record in the Iowa State Senate, Ernst's campaign successfully positioned her as a frontrunner in the primary race.

Ernst was elected to the U.S. Senate in 2014 and subsequently reelected in 2020. During her time in the Senate, she has held various leadership roles, including serving as the chair of the Senate Republican Policy Committee from 2023 to 2025, making her the fourth-ranking Republican in the Senate. Throughout her tenure, Ernst has focused on several key issues, including healthcare reform and fiscal responsibility.

Legislative focus and committees

During her time in the Senate, Joni Ernst has been active in advocating for reforms to major entitlement programs, including Medicare, Medicaid, and Social Security. Her legislative priorities reflect a commitment to addressing fiscal challenges facing these programs while seeking to ensure their sustainability for future generations. Ernst has also been vocal about various economic issues, particularly those affecting Iowa's agricultural sector, which is a significant component of the state's economy.

Ernst's tenure has been marked by her involvement in discussions surrounding trade policy, particularly during the Trump administration. While she supported many of the administration's initiatives, she expressed concerns regarding the implications of the trade war with China for Iowa's farmers and the broader agricultural community. This nuanced stance highlights her commitment to representing the interests of her constituents while navigating the complexities of national policy.

In addition to her focus on healthcare and trade, Ernst has been involved in discussions surrounding environmental policy, particularly in relation to the Renewable Fuel Standard. While she supported the nominations of both of Trump's Environmental Protection Agency administrators, she raised questions about their commitment to maintaining the Renewable Fuel Standard, which is crucial for Iowa's biofuels industry.

Throughout her Senate career, Ernst has served on several committees, where she has contributed to shaping legislation on a range of issues. Her military background has also informed her perspectives on national security and defense, allowing her to engage in discussions about military readiness and veterans' affairs.

As of September 2, 2025, Joni Ernst announced that she would not seek reelection in 2026, marking a significant transition in her political career. Her decision reflects a broader trend among some lawmakers to step back from public office after multiple terms, allowing for new voices and perspectives to emerge in the political landscape.
