Seven Indiana Republican state senators who opposed Donald Trump’s congressional redistricting plan lost their primary elections Tuesday, May 5, to Trump-backed challengers, while Vivek Ramaswamy secured the Ohio GOP nomination for governor with 82.3% of the vote.
Indiana: Trump’s Retribution Campaign Reshapes State Senate
In a test of Donald Trump’s influence over the Republican Party, seven Indiana state senators who defied his push for a new congressional map lost their primary elections Tuesday to challengers endorsed by Trump and his allies. The incumbents—Dan Dernulc (District 1), Linda Rogers (District 11), Travis Holdman (District 19), Jim Buck (District 21), Spencer Deery (District 23), Greg Goode (District 38), and Greg Walker (District 41)—had drawn Trump’s ire in December 2025 after voting against a redistricting plan that would have secured all nine of Indiana’s U.S. House seats for Republicans. Trump’s social media campaign against them framed the vote as a betrayal of the party’s base, and his financial backers poured resources into primary challengers.
How Indiana’s Redistricting Fight Exposed GOP Divisions
The results mark a significant shift in Indiana’s political landscape, where the state Senate remains part-time and often draws less national attention. But the outcome underscores Trump’s ability to leverage his influence over primary voters, even against incumbents who had previously aligned with his policy goals. The seven incumbents were part of a bloc that resisted Trump’s pressure, a move that now appears to have cost them their seats.
Trump’s strategy in Indiana reflects a broader pattern of targeting Republicans who cross him, a tactic that has reshaped GOP primaries in recent years. The losses also signal that Indiana’s congressional map—currently drawn to favor Democrats—may remain unchanged for the foreseeable future, as the state Senate now lacks the votes to override a Democratic-controlled House’s redistricting plan.
Ohio’s GOP Primary: Ramaswamy’s Landslide and the Fading Competition
While Indiana’s results highlighted Trump’s influence over the GOP base, Ohio’s primary delivered a clear victory for Vivek Ramaswamy, who won the Republican nomination for governor with 82.3% of the vote. Ramaswamy, a wealthy biotech entrepreneur and former presidential candidate, faced only one serious challenger, Casey Putsch, a state representative who had also sought to position himself as a Trump-aligned candidate. Despite Putsch’s efforts, Ramaswamy’s dominance in the primary—backed by Trump’s endorsement—solidified his place as the GOP’s nominee for the general election.
Ramaswamy’s victory sets the stage for a highly competitive race against Democrat Amy Acton, a former Ohio Department of Public Health director who won her party’s nomination without opposition. Ohio has not elected a Democratic governor in 20 years, and the state’s political landscape remains heavily Republican. However, Acton’s experience in public health—particularly in a state where healthcare and economic policy will be key issues—could make the race closer than initial polling suggests.
The primary also highlighted the shifting dynamics within Ohio’s GOP. Former Attorney General Dave Yost and Ohio State University football coach Jim Tressel, both of whom had been seen as potential contenders, dropped out before the primary, leaving Ramaswamy as the clear frontrunner. His victory underscores the growing influence of Trump-aligned candidates in the Midwest, even in states where the GOP has traditionally held strong.
Legislative and Electoral Consequences of the Primaries
In Indiana, the fallout from Tuesday’s primary will likely reverberate through the state’s legislative sessions. With seven new senators likely to take office in November, the balance of power in the state Senate could shift significantly, particularly on issues like redistricting and tax policy. Trump’s allies in the Senate may now have the votes to advance his preferred congressional map, though the Democratic-controlled House remains a hurdle.
In Ohio, Ramaswamy’s path to the governor’s mansion will depend on his ability to consolidate support beyond the Trump-aligned base. The general election campaign will likely focus on economic issues, healthcare, and education, areas where Acton’s experience could give her an edge. Meanwhile, Trump’s continued influence over the GOP—demonstrated in both Indiana and Ohio—suggests that his role in shaping the party’s future will remain central, even as other candidates seek to carve out their own paths.
The results from both states reflect a Republican Party still deeply divided between those who remain loyal to Trump and those who seek to distance themselves from his leadership. As the 2026 midterm elections approach, the tension between these factions will continue to shape the GOP’s strategy—and its chances of success.
