President Trump's preferred candidates toppled five Republican incumbent state senators in Indiana on Tuesday night while Vivek Ramaswamy coasted to the GOP gubernatorial nomination in Ohio, a pair of results that underscored the president's unmatched grip on the Republican electorate from the statehouse to the governor's mansion.
The Indiana races were the main event. Eight GOP state senators who voted last year to block a Trump-backed plan to redraw the state's congressional map faced voters for the first time since that defiance. Seven of those incumbents drew Trump-endorsed challengers. Five lost decisively, a sixth race remained too close to call late Tuesday, and only one incumbent managed to survive.
The margins were not close. The New York Post reported that Trump-backed challenger Trevor De Vries topped state Sen. Dan Dernulc by a staggering 75%, 24%. Tracey Powell beat state Sen. Jim Buck 65%, 35%. Brian Schmutzler defeated state Sen. Linda Rogers by 18 points. Michelle Davis beat state Sen. Greg Walker by the same margin. And Blake Fiechter dispatched longtime state Sen. Travis Holdman, in office since 2008 and a member of Indiana Senate leadership, by a 61%, 39% count.
The roots of Tuesday's rout reach back to December 2025. Trump and his allies had pushed Indiana's Republican-controlled Senate to redraw the state's congressional boundaries, a move that could have added two GOP U.S. House seats ahead of the midterms, as Newsmax reported. Twenty-one Republican state senators voted the plan down, handing Trump one of his first significant political defeats of his second term.
The president did not forget. He endorsed primary challengers to seven of the eight incumbents who opposed the maps and were up for reelection this cycle. The White House leaned in hard, with Vice President JD Vance meeting state politicians directly and Trump himself joining by conference call to pressure lawmakers, the Washington Times reported.
Money followed the endorsements. Trump-allied outside groups poured millions into the seven contested races. The New York Post placed the figure at over $10 million. The Washington Times tallied more than $8.3 million. Fox News reported that groups including Club for Growth and Turning Point USA backed the effort, with Club for Growth President David McIntosh telling the outlet:
"We've got to change those old-style Republicans, put in people who will fight, fight against the Democrat gerrymandering."
About $12 million was spent on advertising across the seven races, with most of the money coming from Trump-aligned groups opposing the incumbents, Newsmax reported.
Only one incumbent who defied Trump on redistricting managed to hold on. State Sen. Greg Goode defeated Trump-backed challenger Brenda Wilson in Indiana's District 38 primary. But that race came with an asterisk. A third candidate, Alexandra Wilson, pulled roughly 10% of the vote. The White House had reportedly pressured Alexandra Wilson to exit the race before Tuesday over concerns that her presence on the ballot would confuse voters trying to cast ballots for Brenda Wilson.
The split may have saved Goode. Whether the White House's concern was justified is impossible to prove from the returns alone, but the dynamic illustrates just how granular the president's political operation has become, down to worrying about name confusion in a single state Senate district.
Trump himself had posted on Truth Social before results came in, writing:
"Good luck to those Great Indiana Senate Candidates who are running against people who couldn't care less about our Country, or about keeping the Majority in Congress."
He labeled the incumbents "long seated RINOS." The White House has shown no hesitation in recent months about using presidential authority and influence to reshape political outcomes, and Tuesday's Indiana results suggest the strategy is working at the ballot box.
Sen. Jim Banks (R-Ind.) issued a statement that left no room for ambiguity about the takeaway:
"Everyone in Indiana politics should have learned an important lesson today: President Trump is the single most popular Republican among Hoosier voters."
Banks added that Indiana "is a conservative state, and we deserve conservatives in our State Senate who have a pulse on Republican voters."
Indiana Gov. Mike Braun, who had supported the redistricting effort that the incumbents blocked, called it "a historic night for Indiana." He wrote on X that Republicans "stood with me and President Trump to nominate some great America First conservatives" and said he looks forward to "winning big in November and serving Hoosiers with this team in the statehouse."
Breitbart noted that even one additional incumbent who opposed redistricting, Sen. Rich Niemeyer, appeared likely to lose, despite Trump not endorsing his challenger. Republican attorney Jim Bopp summarized the dynamic plainly: "Republican voters overwhelmingly support Trump, and when they find out Trump has endorsed a particular Senate candidate, they swing their support behind them."
That assessment tracks with what happened Tuesday. The margins were not flukes. They were consistent across races, across districts, and across opponents with varying levels of name recognition and tenure. The message from Indiana's Republican primary voters was clear.
Across the border in Ohio, Vivek Ramaswamy won the Republican gubernatorial primary in what amounted to a formality. The biotech entrepreneur and former 2024 GOP presidential primary candidate entered the race as the front-runner after securing endorsements from both Trump and Vice President Vance. He defeated business owner Casey Putsch, capturing 82.47% of the vote, Breitbart reported.
Vance himself traveled to Ohio earlier Tuesday to cast his ballot for Ramaswamy and give the campaign a last-minute boost before polls closed. It was a visible show of alignment between the White House and the candidate.
Ramaswamy struck an optimistic tone Tuesday night:
"We're going to revive that American Dream in Ohio once again, with lower costs, bigger paychecks and better schools for all Ohioans."
He will face Democrat Dr. Amy Acton in the November general election, a contest that polls suggest could be competitive. The president has been actively shaping the political landscape heading into the midterms, and Ohio's governor's race will be a marquee test of whether Trump's primary dominance translates in a general-election environment.
Ohio also set the stage for a high-profile Senate rematch. Sen. Jon Husted (R-Ohio) ran unopposed in the special election Senate race and will square off against former Sen. Sherrod Brown in November. That contest will test whether Ohio's rightward shift continues or whether Democrats can reclaim ground in the Buckeye State.
On the Democratic side, the attorney general primary produced a result that few will mourn. Former state lawmaker Elliot Forhan, who months earlier had declared he was "going to kill Donald Trump" by securing a legal conviction "resulting in a sentence, duly executed, of capital punishment", lost to Columbus attorney John Kulewicz by a 66%, 33% margin.
Kulewicz had condemned Forhan's comments as "disgraceful." Ohio Democratic primary voters apparently agreed. Kulewicz will face Republican Keith Faber in November. Forhan's rhetoric may have been intended as legal bravado, but voters in his own party rejected it decisively, a small sign that reckless language about the president carries a political cost even within Democratic ranks.
Tuesday also brought a result in Michigan. Democrat Chedrick Green won a special election to fill Rep. Kristen McDonald Rivet's former state Senate seat, securing the Democratic Party's majority in the Michigan Senate. That outcome drew far less national attention than the Indiana and Ohio results, but it matters for the balance of power in Lansing.
For Republicans, the Michigan loss is a reminder that the broader political environment is not uniformly favorable. Trump's dominance within Republican primaries is undeniable. Whether that energy extends to general elections in competitive states remains the open question heading into November.
The Indiana results are the night's clearest story. A group of Republican state senators defied the president on redistricting. Trump endorsed their opponents, his allies spent millions, and voters delivered landslide defeats to all but one of the incumbents. The speed and scale of the result will not be lost on Republican officeholders in other states who may be weighing whether to cross the president on future priorities.
Just the News reported that the Indiana Senate had voted down the proposed congressional maps in December despite pressure from state leaders and national Republican figures. That defiance lasted roughly five months before primary voters rendered their verdict.
The spending was enormous for state Senate races. The organizational effort was real. But money and endorsements alone do not produce 50-point margins. Republican voters in Indiana chose Trump's candidates because they agreed with the president, not because they were tricked by ad buys.
That is the lesson Tuesday's losers should take to heart. And it is the lesson every Republican officeholder in America received, whether they wanted it or not.
