Rep. Andy Barr is a prodigious fundraiser whose House district includes Kentuckys second-largest city. Former state Attorney General Daniel Cameron enjoys broad name recognition after two statewide runs. And Nate Morris is a largely unknown entrepreneur positioning himself as a political outsider.

But looming over the three-way Republican primary for Kentuckys open Senate seat are two defining figures of the modern GOP President Donald Trump and former Senate Majority Leader Mitch McConnell, whose legacy is at the center of the increasingly bitter contest to succeed him. 

Barr, Cameron and Morris are campaigning as fierce Trump loyalists, and they each know that an endorsement from the president would provide any candidate in this reliably red state with a powerful boost.

All three candidates also have ties to McConnell, a towering presence in Kentucky politics for decades and the longest-serving leader in Senate history. 

Camerons links to the commonwealths senior senator go back to his days at the University of Louisville, when he participated in the McConnell Scholars Program. He later served as his legal counsel. Barr has worked on legislation with McConnell as a fellow member of the Kentucky delegation. And Morris interned for McConnell and held a fundraiser for him in 2014, according to The New York Times.

Both Barr and Cameron have sought to distance themselves from the 83-year-old senator, who announced in February that he would not seek an eighth term.

Morris, however, has gone further, openly trashing McConnell in ads, in interviews and at last weekends Fancy Farm fundraiser in western Kentucky.

Who here can honestly tell me that its a good thing to have a senior citizen who freezes on national television during his press conferences as our U.S. senator? Morris asked the audience at Fancy Farm, referring to McConnells recent health struggles. It seems to me, maybe, just maybe, Mitchs time to leave the Senate was a long time ago.

Vilifying McConnell might be a way to win over Trump, with whom the senator has long had a fraught relationship. McConnell blamed Trump for the Jan. 6, 2021, assault on the Capitol, though he voted against convicting him at his second impeachment trial. 

We know that Nate Morris strategy might not be to just attract Kentucky voters, but also to attract that national attention, said Amy Wickliffe, a Republican strategist who is not aligned with any of the Senate hopefuls. And its no secret that all three candidates are seeking President Trumps endorsement. So a lot of this messaging youre seeing here is about who can win that endorsement.

But demonizing the man Kentucky voters have repeatedly sent back to the Senate, often by double-digit margins, carries risks as well. 

Mitch McConnell has been a stalwart & in building the Republican brand in Kentucky since 1984, said John McCarthy, a Republican National Committee member who is backing Barr. Theres a lot of people who have been helped by his office, and the commonwealth has punched far above its weight class because of his longevity.

McCarthy said a strategy of running against McConnell may give you a cornerstone to a base in a low turnout primary, but I dont think its going to be enough to carry the day.

Theres no guarantee that the White House will weigh in on the race. But that hasnt stopped Barr, Cameron and Morris from emphasizing their unyielding allegiance to the president and his MAGA agenda.

This president is working for the American people, and now he needs reinforcements in the Senate, Cameron, who had Trumps support in his unsuccessful 2023 run against Democratic Gov. Andy Beshear, told the Fancy Farm crowd. Trumps return to the White House signified a victory for common sense and a loss for autopens and incompetence. 

Morris has adopted a coarse tone that evokes the style of some of Trumps most ardent supporters. In his Fancy Farm remarks, he addressed Barr and Cameron directly. 

Perhaps you could both show us the seat of your britches so we can finally understand where Mitch McConnells hand goes, he said as a wave of boos fluttered through the crowd.

Wickliffe said such attacks could backfire.

From some of the feedback Im hearing in the early days of this campaign, the bashing and the nastiness might be wearing a little thin, Wickliffe said. Eventually voters will want to hear what youre going to do for Kentucky and for the nation, not just why the next guy is bad.

Morris calls himself a Trump America-first conservative. He announced his candidacy on Triggered, a podcast hosted by Donald Trump Jr., and has won praise from MAGA influencer Charlie Kirk. But, Morris opponents note, he donated $5,000 to former South Carolina Gov. Nikki Haleys PAC. (The contribution was made in 2021, long before she became Trumps rival for the 2024 GOP presidential nomination.) 

Barr, who has represented the Lexington-centered 6th District since 2013, used his time at Fancy Farm to highlight his votes in support of Trumps legislative priorities. 

Some politicians like to say, Im a Trump guy, Barr told the audience. They talk about supporting the president. But Im the only candidate in this race whos actually doing it day in and day out in Congress. My opponents like to talk about the one big, beautiful bill. I wrote it and helped to pass it.

Cameron and Barr both have political track records, which cuts both ways, said D. Stephen Voss, a political scientist at the University of Kentucky. 

They face the usual dilemma that career politicians face when running against someone who promises to be a newcomer, Voss said. Morris can be all things to all people. & Theres not really much of a track record to push back on.

Morris has begun running ads introducing himself to voters as the son of a single mother who built a waste-management software firm, Rubicon Technologies. Hes sought to cast himself as a successful entrepreneur who will bring a business outlook to politics, in the mold of Ohio Sen. Bernie Moreno, who recently endorsed Morris. 

But Morris business record, including his companys struggles and its past support of diversity initiatives, has provided fuel for his opponents attacks. Out here in west Kentucky, we have a name for someone who opposed President Trump, supported [Black Lives Matter] and pushed DEI a Democrat, Barr said.

An internal polling memo provided by the Barr campaign suggests Morris early ad blitz has yet to pay dividends. The memo did not include polling numbers for the GOP primary but said Camerons lead has continued to shrink, with Barr poised to capitalize.

Barr, a member of the House Financial Services Committee, holds a commanding fundraising lead: He brought in $1.4 million in the second quarter of the year, bolstering his cash on hand to $6.1 million as of June 30. Camerons fundraising has lagged, reporting a second-quarter haul of $386,000, with $532,000 in the bank. Morris did not file a fundraising report since he did not register his campaign until after the deadline. His campaign said the wealthy businessman will both invest his own funds and seek to raise money from donors.

Kentucky House Minority Floor Leader Pamela Stevenson of Louisville is the only Democrat to formally launch a Senate bid. (Beshear said in February that he does not intend to run.)

Kentucky hasnt elected a Democratic senator since Wendell H. Ford won a final term in 1992. And Inside Elections with Nathan L. Gonzales rates the current race Solid Republican. 

Kentucky is a red state and we are confident that no matter what radical, far-left Democrat the Party props up as their nominee voters will elect a strong conservative to support President Trumps agenda in Washington, National Republican Senatorial Committee spokeswoman Joanna Rodriguez said in an email.
