A Kentucky voter who backed President Donald Trump is now publicly blasting the president’s campaign to remove Rep. Thomas Massie from office — calling it a “slap in the face” to voters in the state.

The backlash comes as Trump intensifies his war against Massie ahead of Tuesday’s explosive Republican primary election in Kentucky, a race that has now become the most expensive House primary battle in American history.

According to reports, at least $25.6 million has flooded into the contest, with massive sums being spent to defeat Massie and boost Trump-backed challenger Ed Gallrein.

But despite Trump’s aggressive attacks, not every MAGA voter appears happy about it.

Speaking to The Wall Street Journal, Kentucky voter John Detherage — who says he voted for Trump — criticized the president’s effort to effectively choose the state’s next congressman.

“We love our congressman,” Detherage said.

“And the fact that the president is trying to pick our next congressman for us is kind of a slap in the face to Kentuckians.”

Massie became one of Trump’s top enemies after teaming up with Democratic Rep. Ro Khanna to push for the public release of the government’s Jeffrey Epstein files.

That effort ultimately helped lead to passage of the Epstein Files Transparency Act — a move that reportedly enraged Trump and many of his allies.

Since then, Trump has repeatedly attacked Massie publicly.

As recently as Sunday morning, the president blasted the Kentucky Republican on social media, calling him a “bum,” a “troublemaker,” and a “true negative force.”

Trump also urged Republican voters to remove Massie from office entirely.

The political fight has rapidly escalated into one of the nastiest intraparty battles of Trump’s second presidency.

What makes the race especially unusual is the coalition now lining up behind Massie.

Despite frequently clashing with Democratic leadership, Massie’s push for Epstein file transparency earned him support from anti-establishment voters, libertarians, civil liberties advocates, and even some progressives who believe the public deserves access to information tied to the late financier Jeffrey Epstein.

At the same time, the race has also attracted enormous outside spending.

Reports indicate that at least $6.6 million of the anti-Massie spending has come from pro-Israel groups angered by Massie’s criticism of Israel’s military actions in Gaza.

Human rights organizations have heavily criticized the Gaza siege, with some groups labeling the humanitarian crisis there a genocide — language that remains politically explosive in Washington.

For critics of Trump, the Kentucky primary is increasingly being viewed as a loyalty test inside the Republican Party.

For Trump supporters like Detherage, however, the situation appears more complicated.

Many voters who still support Trump broadly are now wrestling with whether the president has gone too far in trying to politically destroy Republicans who challenge him on certain issues.

And with millions pouring into the race and tensions inside MAGA circles escalating by the day, Tuesday’s primary is now being watched nationally as a potential referendum on Trump’s continued grip over the Republican Party.
