Trump Can't Escape Mitch McConnell in Kentucky

President Donald Trump backed Representative Andy Barr in Kentucky‘s Republican primary for Senate, and Barr won. It was a clean endorsement, a clear result. But the race itself told a different story about Trump’s power to reshape the Republican Party.

Both leading candidates, Barr and former Kentucky Attorney General Daniel Cameron, had built their careers inside Mitch McConnell‘s political machine. The only candidate who ran explicitly against McConnell dropped out weeks before voting.

McConnell is retiring after four decades in the Senate, but even as Trump picked the winner, McConnell had already shaped who could run.

A Win for Trump, With Limits

Trump’s endorsement of Barr came early this month and proved decisive. "He positioned himself as the candidate most aligned with the Trump wing while also looking like the most electable, best-funded Republican in the race," T.J. McCormack, a radio host and GOP strategist, said in an interview with Newsweek

But Barr already held an edge before the president weighed in. A late March Emerson College poll conducted for Fox 56 Lexington showed him leading Daniel Cameron 28 percent to 21 percent-a seven-point margin.

"The Trump endorsement is sort of the final punctuation mark on trends that were already developing," Stephen Voss, a political scientist at the University of Kentucky, told Newsweek.

McConnell’s Imprint on the Field

Barr spent thirteen years in Congress, having once interned under McConnell. Cameron previously worked as legal counsel to the senator. Both men had roots in McConnell’s network, and both understood what that meant for how they could campaign.

In their final forums before voting, both candidates praised McConnell. Cameron pointed to the $65 billion McConnell’s office said it had brought to the state over decades. Barr invoked McConnell’s legacy, saying Kentucky needed to continue punching above its weight in national politics. Neither candidate attacked him directly. Both seemed to recognize that openly breaking with McConnell could alienate voters and party officials who had benefited from his work.

Barr thanked Trump in his victory speech Tuesday night, but he also praised McConnell "for his decades of service to our Commonwealth and this country," to cheers and applause.

Nate Morris ran a different race. He was the third major candidate, backed by $10 million from Elon Musk and support from Vice President JD Vance and Donald Trump Jr. Morris positioned himself as the anti-establishment choice. His campaign called Barr and Cameron “McConnell’s boys” and showed a cardboard cutout of McConnell in the trash. For weeks, it seemed plausible that Morris could open a lane by being willing to say what others would not.

Then Morris dropped out two weeks before voting. Trump offered him an ambassadorship, and he took it. The anti-McConnell candidate vanished from the ballot.

Why the Anti-McConnell Lane Failed

McConnell is considered such a titan in Kentucky that lawmakers voted to place his statue alongside Abraham Lincoln's in the Capitol. After overcoming polio as a child, he rose to become the longest-serving Senate leader in history and helped secure a conservative majority on the U.S. Supreme Court. He brought more than $65 billion back to the state, according to his office. He also established Republican dominance in a state where Democrats once competed statewide.

But McConnell broke with Trump after the January 6 attack on the Capitol. More recently, he opposed Trump's nominees, including Pete Hegseth as defense secretary and Robert F. Kennedy Jr. as health secretary, and pushed for continued military assistance to Ukraine. These breaks with the president made McConnell unpopular with the Trump voters who now dominate Republican primaries.

Yet Morris lagged behind Barr and Cameron despite his resources and explicit anti-McConnell message. Voss, the University of Kentucky political scientist, saidthat the GOP's problem was that every major candidate was running as pro-Trump.

"Barr, Cameron, and Morris all claimed Trump loyalty. When all three candidates were aggressively pro-Trump, Morris could not differentiate himself through anti-McConnell messaging alone," he said.

What It Means for the GOP After McConnell

Trump may have helped decide who replaces Mitch McConnell. But he did not fundamentally change the kind of Republican who could win the seat.

But despite some goodwill toward McConnell, many Republicans are ready for a change. Barr will go to the Senate as a product of McConnell’s system, though it is expected that he will pursue Trump’s agenda and align himself with the president’s priorities.

When Trump endorsed him early in May, Barr said he would stand with the president “100 percent to deliver for Kentucky and to keep Making America Great Again.”

In one of his final forums before voting on Tuesday, Barr acknowledged McConnell’s work establishing Republican dominance, but was quick to differentiate from his mentor.

“I am my own man,” he said.
