What Happened

President Donald Trump's so-called revenge tour got its first real test on May 5, when Indiana held primaries that put Trump's endorsement power directly on the line. The core question: Can Trump successfully punish Republicans who defied him, or have his approval ratings and an unpopular war in Iran eroded his ability to move primary voters?

Recap

Trump's campaign to reshape the Republican Party in his image has three major fronts this month.

Indiana was the first test. Trump backed challengers against seven of eight GOP state senators who voted to block his mid-decade congressional redistricting push, a plan designed to shore up Republican margins in the House ahead of November. Trump posted on Truth Social on primary day, framing the incumbents as disloyal: "There are eight Great Patriots running against long-seated RINOs — Let's see how those RINOs do tonight!"

He had been even sharper earlier, singling out Indiana Senate President Rod Bray by name: "Headed by a total loser named Rod Bray, every one of these people should be 'primaried,' and I will be there to help!"

Kentucky is next, with the May 19 primary putting Rep. Thomas Massie against Trump-backed challenger Ed Gallrein, a former Navy SEAL. Trump endorsed Gallrein in March, and Massie was characteristically dismissive. "I ain't reading" the endorsement post, Massie said, adding: "I can win this race if I'm outspent 2 to 1. When you got the truth on your side, you've got the high ground."

Louisiana rounds out the revenge tour's near-term calendar, where Trump has backed a challenger to Sen. Bill Cassidy, another Republican he has long viewed as a political adversary.

The political backdrop complicates Trump's position. The Politico piece notes that success will be harder this cycle, with Trump managing an unpopular war in Iran, sinking approval ratings, and voter discontent on economic and immigration issues. One analyst quoted in the piece put it bluntly: "The [Trump] endorsement just isn't moving voters."

Indiana Results and the Revenge Tour's First Verdict

The results told a different story. CNN confirmed that at least five of the seven Trump-backed challengers defeated GOP incumbent state senators who had voted against redistricting. NBC News projected the same outcome. Politico's own follow-up framed it as a demonstration that "his endorsement remains the gold-standard of GOP politics."

The IndyStar reported that Trump's Indiana footprint was broader than the redistricting fight alone. He made 19 total endorsements in the state, including backing incumbent senators who had supported his redistricting push. Trump-backed challenger Tracey Powell defeated incumbent state Sen. Jim Buck in Kokomo, with Buck conceding on audio captured by the IndyStar.

Hill & Administration Take

The Redistricting Fight

The Indiana primaries were downstream of a specific legislative dispute: Trump's push for mid-decade congressional redistricting in states where Republicans control the legislature. The goal was to redraw lines in ways that could expand the GOP's House majority before November. When Indiana's Republican-controlled state senate blocked the effort, Trump treated it as a personal betrayal and moved to clear out the dissenters.

The Massie Factor

Massie's primary is the most ideologically layered race in the revenge tour. Al Jazeera's longform piece published April 28 provides the deepest historical context: in 2020, Trump called for Massie to be thrown out of the Republican Party, then reversed course in 2022 and endorsed him over a primary challenger. Now Trump is targeting him again. Al Jazeera described Massie as a "seven-term congressman known for his staunch conservatism and his willingness to buck the president's priorities."

That history makes the Kentucky race a more complicated read than Indiana. Trump is not going after a moderate or a Democrat-leaning Republican. He is going after one of the most conservative members of the House, whose resistance to Trump has been rooted in libertarian-leaning fiscal and foreign policy positions rather than any alignment with Democrats.

NBC News cited AdImpact advertising data showing that 70 percent of TV ads in the Indiana, Louisiana, and Kentucky races mentioned Trump by name, including ads by candidates Trump is trying to defeat. Even Sen. Bill Cassidy ran an ad featuring a supporter saying he "worked with President Trump to pass tax cuts," illustrating how thoroughly Trump's brand dominates both sides of these primaries regardless of his endorsement. Massie has also been very vocal on the Epstein files. In February he publicly asked, "When will we see justice?" He went on to say, "We should be proud of this country because we have a system of Justice that works, and yet we do not," 

What the Media Is Reporting

CNN's takeaways piece confirmed the Indiana results and flagged the May 19 Kentucky race as the next and "clearest" test of Trump's endorsement power, noting that Massie represents a different kind of challenge than the Indiana state senators. NBC News reporters Bridget Bowman, Matt Dixon, Henry J. Gomez, and Melanie Zanona named Massie as Trump's top target in the May cycle and called it "the toughest fight of his political career." The New York Times brought in on-the-ground voter voices that complicated the narrative, including a retired steelworker who identified as a Trump supporter but said of the revenge campaign: "I was under the understanding that he wanted states to regulate themselves, take care of themselves, but now he's coming back with this revenge type of thing and I'm not happy with that." That grassroots Republican skepticism is largely absent from the national framing of Indiana as a clean Trump win.
