Trump's Revenge Tour: Massie Ousted, Cornyn Targeted as GOP Critics Face Primary Challenges

Donald Trump took another prize in his bloody revenge tour against wayward Republicans on Tuesday as Rep. Thomas Massie, one of his few remaining GOP critics left in office and a leader in the push to release the Epstein files, was ousted in a primary contest in Kentucky.

Massie, like Sen. Bill Cassidy before him, went down in a bruising intra-party fight that saw an ally of Trump boosted to victory with the president’s emphatic endorsement and support from the broader pro-Trump establishment. Cassidy’s crime — having voted to convict Trump in 2021 over the Jan. 6 Capitol riot.

Massie’s defeat was especially exciting for AIPAC, the major pro-Israel lobby in Washington, which counted the Kentucky congressman as the lone remaining vocal critic of Israel within the Republican congressional delegations after the departure of Rep. Marjorie Taylor Greene in January.

But while the libertarian-minded Massie never voted alongside Republicans during the lower chamber’s legislative fights in 2025, a warning shot was fired at the White House from the other side of Capitol Hill on Tuesday, hours before voters delivered the results in Kentucky. For the first time, the Senate advanced a War Powers resolution aimed at restricting Trump’s war-making against Iran — with Cassidy’s deciding vote.

Before Tuesday’s vote, the Trump revenge campaign had yet to backfire.

In Indiana, he successfully led a purge of state lawmakers who resisted his gerrymandering demands, a victory that had the dual effect of getting rid of noncompliant Republicans and scaring others around the country into line. Even in Massie’s case, the congressman can do little more to hinder Trump’s agenda in the House than he already has.

In Cassidy’s case, however, the 53-47 Senate margins allow him to become a chaos agent, if he so desires.

An ally of the GOP establishment and a supporter of the Senate’s institutions, he won’t, but the Louisiana Republican’s newfound freedom from Trump’s yoke will allow him to act against the White House more often when other GOP senators find the prospect too politically risky. His heel turn may in the end closely resemble that of Sen. Thom Tillis, the North Carolina Republican who has seen fit to increasingly oppose the president after he broke with Trump in 2025 over the “Big, Beautiful Bill” and then subsequently declined to run for re-election when it became clear he’d face a Trump-backed primary opponent.

Tillis gave the White House a massive headache this year when he used his position on the Banking committee to block the nomination of Kevin Warsh to the Federal Reserve for weeks while he demanded that the Department of Justice drop its attempt to prosecute Jerome Powell, the current Fed chair, as part of a White House-directed pressure campaign against the chairman. He eventually forced the DOJ to back down.

With Cassidy’s vote on the War Powers resolution on Tuesday, it’s clear that the number of rabble-rousing Republicans in the upper chamber is growing.

What happens to that 53-47 margin if John Cornyn is added to the mix?

Texas’s hugely-expensive GOP Senate runoff contest is now less than a week away. Members of Senate Republican leadership have made no secret about which side they’re on, and spent months lobbying Trump to endorse the incumbent Sen. John Cornyn as he battles the scandal-plagued Ken Paxton in an expensive mud-slinging contest that has so far cost the party’s donors nearly $100 million in the state — all to decide the Republican nominee, who will then go on to spend even more money in the general election.

Cornyn is battling his own reputation as a wishy-washy supporter of the president in the state, and Trump finally drove the dagger in the senator’s back on Tuesday as he marked his next target on the vengeance crusade.

Trump wrote of Cornyn on Truth Social just as voting began in Kentucky: “John Cornyn is a good man, and I worked well with him, but he was not supportive of me when times were tough...John was very late in backing me in what turned out to be a Historic Run for the Republican Nomination, and then, the Presidency, itself.”

Cornyn’s defeat next Tuesday could have a ripple effect across a GOP Senate caucus where discontent with the White House is already bubbling close to the surface. While adding the veteran Texas senator to the list of possible roadblocks in the chamber itself, the loss could also further fray the president’s relationship with Senate Majority Leader John Thune just as Republicans in both chambers are gathering to debate a path forward for a second budget reconciliation bill in the vein of Trump’s 2025 “Big, Beautiful Bill.”

While the president has comparatively fewer legislative priorities to cram into this new package, it represents the best and possibly only hope of authorizing further ICE funding this year after Republicans abandoned negotiations with Democrats over reforms to the Trump mass deportation machine.

One Iowa political blogger followed on X by Sen. Mike Lee, one of the president’s top loyalists in the upper chamber, had a stern warning for those allies of the White House on Wednesday after Massie’s defeat: “Trump pissed in his own Cheerios and it’s going to cause the final 7 months of this Congress to be brutal for him.”

If Cornyn adds himself to the list of Republicans straying from the White House’s golden path, that prediction will likely turn out to be true.
