One candidate’s call for a moratorium on all migration could help him with the MAGA base.
As the battle for the post-Trump Republican Party heats up, one 2026 midterm contest offers a useful look at where the MAGA movement and the GOP are headed on the foundational issue of immigration.
In the race for the U.S. Senate seat being vacated by former Senate Majority Leader Mitch McConnell (R., Ky.), three candidates with differing views and records on immigration are vying for the GOP nomination — an all-but-guaranteed ticket to Washington, D.C., given Kentucky’s overwhelmingly Republican lean.
Two contenders, former state Attorney General Daniel Cameron and Lexington-area congressman Andy Barr, are longtime allies of McConnell and are widely viewed as close to the state’s powerful GOP establishment. The third, businessman and former political fundraiser Nate Morris, is a self-proclaimed “disruptor” and first-time candidate running an unabashedly pro-Trump, anti-McConnell, and anti-mass migration campaign.
Both Cameron and Barr are known quantities in the Bluegrass State. Cameron, a McConnell protégé, was the Republican gubernatorial nominee in 2023 but was defeated by Democratic incumbent Andy Beshear in a bitter and historically expensive general election contest. Barr, first elected to Congress in 2012, has made a name for himself on Capitol Hill as a top lieutenant of House Republican leadership and as a leading congressional voice on banking regulation.
Morris, on the other hand, has sought to use his outsider status to separate himself from the Republican establishment — embodied by McConnell — on issues ranging from aid to Ukraine to immigration. A close personal friend of Vice President JD Vance, Morris was encouraged by Vance to run for the Senate last year, a source familiar with the conversation told NR.
Since his entrance into the race, Morris has attracted media attention and generated a large online following among young MAGA-aligned activists through his call for a moratorium on all migration. Morris has argued that high levels of immigration — particularly the tens of millions of migrants who entered the U.S. both legally and illegally under the Biden administration — constitute threats of “existential immediacy” to America’s cultural cohesion and national identity.
The race has remained largely stable for months; Cameron has led nearly all public polls, with Barr taking second and Morris a distant third. Still, allies of Morris are confident that his focus on immigration will boost his standing among grassroots pro-Trump voters, sway the approximately half of Kentucky Republicans who still have no opinion of him, and set him apart from his rivals as the race’s MAGA standard-bearer ahead of the May 19 primary.
More than five months out from the primary, the race’s dynamics are still deeply in flux. Lingering disappointment from Cameron’s gubernatorial loss in bright-red Kentucky and his significant fundraising struggles have fanned concerns among insiders that his early polling lead is soft, and have prompted establishment-aligned GOP donors to shift their focus to Barr.
McConnell has yet to endorse in the race, but two Republican sources with direct knowledge of the situation, who are unaffiliated with the three campaigns, told NR that the former Senate majority leader had made clear in private conversations that he backed Barr, and was steering his donors toward the congressman.
A source close to McConnell said that “Senator McConnell has not endorsed in this race nor does he plan on doing so.”
While President Trump has so far also declined to publicly weigh in, the ideological contours of the race have begun to emerge in the candidates’ respective endorsements. Barr has secured endorsements from top Republicans on Capitol Hill, including House Majority Leader Steve Scalise (R., La.), Representative Elise Stefanik (R., N.Y.), and former House Appropriations Chairman Hal Rogers (R., Ky.).
Morris, by contrast, has cultivated support on the GOP’s right flank. Backed by staunch Trump allies and migration hardliners like Senators Jim Banks (R., Ind.) and Bernie Moreno (R., Ohio), Morris was the last candidate to receive Charlie Kirk’s endorsement before the iconic conservative activist’s assassination. Kirk traveled to Kentucky to rally with Morris just weeks before he was shot dead by a leftist gunman in September, and cited Morris’s opposition to immigration as a principal reason behind his support for the candidate.
“We’re only just beginning to feel the long-tail consequences of unfettered migration into this country,” Morris told NR in a statement explaining his support for limiting immigration into the United States. “Wages are being depressed, housing is more expensive, our schools, roads and hospitals are more congested — and every single one of those problems disproportionately affects middle-class Americans.”
Immigration’s potency as a GOP issue nationally — and as one of the top items on the Trump administration’s policy agenda — makes this race an important one to watch as the candidates stake out divergent positions on the issue.
Morris’s call for an immigration moratorium has drawn wide attention in part because it is historically unusual among Republican politicians, most of whom typically concentrate their ire on illegal immigration. While progressive and center-right critics of curtailing legal immigration warn that doing so could have significant economic ramifications, proponents argue that record-high immigration waves of recent years and America’s enormous illegal immigrant population necessitate steep cuts to migration levels.
Daniel Di Martino, a fellow at the Manhattan Institute and doctoral student in economics at Columbia University, argued that an immigration moratorium would “crush the economy to the tune of $6.9 trillion over 30 years and cost the federal government $6.6 trillion in additional debt.”
“We need better immigration policies that prioritize legal high-skilled immigrants, and reduce low-skilled immigration, not ending the promise of America altogether,” Di Martino contended in a statement to NR.
Barr’s record of advocating for higher numbers of guest worker visas, his support for granting legal status to DACA recipients, and his description of GOP immigration skeptics as “nativists” have provided political fodder to his opponents and have given immigration additional staying power as the race’s top issue.
A spokesman for the Barr campaign did not respond to a question about the candidate’s views on legal immigration levels, instead telling NR that the congressman had “supported President Trump’s border security policies every step of the way since his first term.”
“Andy led the legal effort to defend Trump’s authority in court to build the wall, and voted for the toughest border security bill in history that Trump signed into law earlier this year,” the spokesman said, referring to the Laken Riley Act, which received unanimous support from congressional Republicans along with the backing of some Democrats.
Immigration’s status as the race’s defining issue was further reinforced after last month’s attack on two National Guardsmen by a recent Afghan migrant in Washington, D.C., which left one soldier dead and prompted the president to announce a permanent ban on immigration from “Third World Countries.”
In the immediate aftermath of the fatal shooting, a 2021 video of Barr calling on then-President Joe Biden to expand Afghan immigration — following Biden’s botched withdrawal of U.S. forces from the country — went viral on X, garnering more than 2 million views. The video, in which Barr argued the U.S. had an “obligation” to grant refugee status to Afghans who assisted American forces, was circulated by prominent MAGA-aligned voices like Donald Trump Jr. and Turning Point USA.
In a statement to NR, a spokesman for Cameron accused Barr of being “strongly supportive of opening wide our borders to unvetted Afghans during Biden’s reckless and dangerous withdrawal,” and, pointing to Morris’s 2014 receipt of an award from the World Economic Forum and his affiliation with the Council on Foreign Relations, argued that Morris “doesn’t have any real beliefs” and “has zero credibility as a conservative.”
“Daniel Cameron has by far the most conservative record on illegal immigration,” the spokesman said, citing Cameron’s lawsuits challenging Biden-era border policies when he was attorney general. The campaign did not respond to a question about Cameron’s views on legal immigration and an immigration moratorium.
Granted anonymity to provide insight into Trump World’s thinking on the primary, a longtime Trump political adviser told NR that “no race in the country is a more clear proxy war between the MAGA base and the establishment than this one.”
