At least five Indiana state senators who voted against President Trump's congressional redistricting push lost Republican primaries Tuesday to challengers the president endorsed, thinning the caucus that blocked the map even as Senate President Rodric Bray survived. Voters in Ohio nominated former biotech executive Vivek Ramaswamy for governor and former Sen. Sherrod Brown for the U.S. Senate, and Democrats kept control of the Michigan state Senate with a special-election win in the Saginaw Bay area.

The Indiana results convert Trump's revenge campaign, previewed in Monday's edition, into a concrete reordering of the statehouse caucus that defied him. They also set the field for two of the most expensive 2026 contests, in a state that has not elected a Democrat as governor in 20 years.

Indiana: the ouster lands

Five Indiana Republicans who voted against redrawing the state's U.S. House map lost their primaries to Trump-endorsed challengers, according to Associated Press projections cited by CBS News. A sixth Trump pick won an open seat vacated by another redistricting opponent. One incumbent the president targeted survived; a final race was too close to call late Tuesday.

The defeated included state Sen. Travis Holdman, a longtime GOP leadership member, who lost to Trump-endorsed Blake Fiechter. Holdman stood by his vote. "Revenge and retribution is not a Christian value," he said.

Bray, who led the 21 Republicans who sank the map in a 40-10 chamber, is not on the ballot until 2028, but his leadership post could be at risk. "It is what it is," Bray told CNN of Trump's threats, adding that he has "no regrets" and that "Indiana's going to do things the way Indiana needs to do them." Trump in January vowed: "We're after you Bray, like no one has ever come after you before!"

Tracking firm AdImpact counted roughly $13.5 million in advertising for the Indiana state Senate primaries this cycle, against just under $300,000 two years ago. Bray estimated $9 million flowed in from out-of-state groups aligned with the president.

Ohio: two general elections set

Ramaswamy, 40, defeated YouTube personality Casey Putsch for the Republican gubernatorial nomination, NBC News projected, and will face Democrat Amy Acton, the former state health director who ran unopposed. Ramaswamy's running mate is state Senate President Rob McColley; Acton's is former Ohio Democratic Party chair David Pepper. Republican Gov. Mike DeWine is term-limited.

Ramaswamy has raised $25 million from donors and put in $25 million of his own money, leaving him with more than $30 million on hand to Acton's $5 million. He has been on television for weeks as part of an initial $10 million ad buy, making the race likely the most expensive in Ohio history.

In the Senate primary, Brown, 73, beat software consultant Ron Kincaid and will face appointed Republican Sen. Jon Husted, 58, in a special election for the seat JD Vance vacated for the vice presidency. Brown lost his 2024 reelection to car dealer Bernie Moreno by 4 points and was recruited back by Senate Minority Leader Chuck Schumer. Brown reported $17 million on hand as of mid-April; Husted reported $8.1 million.

Michigan: the chamber holds

Democrat Chedrick Greene, a Marine veteran and firefighter, defeated Republican Jason Tunney in a special election for Michigan's 35th Senate District, NBC News projected, keeping Democrats' 20-18 Senate majority intact. With 55 percent of the expected vote in, Greene led by 22 points in a district Kamala Harris carried by less than a percentage point in 2024. Gov. Gretchen Whitmer rallied for Greene last week; former Transportation Secretary Pete Buttigieg also campaigned with him.

The counterpoint

All four primary-night reports come from lean-left outlets, CBS News and NBC News. Conservative outlets and Trump-aligned commentators had not posted broad assessments of the Indiana races or the Ohio matchups by press time. The Democratic Governors Association, in a statement to NBC, called Ramaswamy "an out-of-touch presidential also-ran whose harmful agenda would drive costs even higher."

The next test for Trump's intra-party enforcement comes in the Indiana Senate Republican caucus itself, which will choose whether to keep Bray as president when it next meets.
