Voters in Ohio and Indiana participated in primary elections on May 5, 2026, testing Republican loyalty to President Trump and Democratic enthusiasm. Trump's political operation targeted Indiana state senators who opposed redistricting, while economic concerns like high gas prices dominated discussions in Ohio. Key races for governor, U.S. Senate, and House seats saw several outcomes called by the Associated Press.
Primary contests in Indiana and Ohio highlighted divisions over gerrymandering and Trump's agenda. In Indiana, Trump's operation sought to oust seven Republican state senators who blocked a redistricting push to add more GOP seats in the House. Five of the incumbents were defeated, with only State Sen. Greg Goode fending off challengers, according to Associated Press race calls. State Sen. Spencer Deery criticized the White House involvement, saying, “What is being set up here is the potential model for any party to raise ridiculous amounts of money in D.C. and then to use that to try to control the states. That undermines the Constitution without a law. It undermines the 10th Amendment and the ability of states to make their own decisions.” Trump ally Marty Obst countered, “This was a top political priority of President Trump's and [he] was very clear about that. And the bottom line is there's consequences and accountability to those actions.”Both Indiana House incumbents Rep. Jim Baird and Rep. André Carson won their primaries. Baird, who has Trump's endorsement, overcame challenges despite lower fundraising. Carson, the longest-serving incumbent in the state since 2009, prevailed amid calls for new Democratic leadership.In Ohio, early voting showed more Democratic primary ballots cast than Republican by an 11% margin, signaling enthusiasm. Former state health director Amy Acton ran unopposed for the Democratic gubernatorial nomination, while biotech entrepreneur Vivek Ramaswamy won the Republican primary. Incumbent Republican Sen. Jon Husted faced no opposition, and former Democratic Sen. Sherrod Brown easily won his primary.Voters expressed frustration over rising costs, with gas prices nearing $5 a gallon due to the U.S. war with Iran. Gas station clerk Kimberly Thompson noted customers struggling, saying, “When gas gets this high, we have many customers and people that'll stand in the parking lot asking for money or coming in with gas cans.” Architect Michael O’Neill highlighted childcare and healthcare burdens, adding, “What I've noticed is I feel like I'm doing better financially than ever before, and yet we're still barely getting by.” Property taxes also emerged as a top concern.
