Thomas Massie

GOP Rep. Thomas Massie is the long-standing incumbent of Kentucky’s 4th Congressional District. 

Massie faces former Navy SEAL Ed Gallrein in the upcoming GOP primary.

First elected in 2012 after a stint as the Lewis County judge/executive, the Garrison, Kentucky native is an ideological libertarian and an ally of Sen. Rand Paul.

In Congress, Massie is known for his libertarian-leaning positions, especially on fiscal and foreign policy, reducing federal spending, and protecting civil liberties like gun rights. Massie has consistently advocated for reducing the overall size and scope of the federal government, voting against large spending bills introduced by both Democrats and Republicans.

Although many of Massie’s legislative proposals do not become law, his influence in Congress mainly comes from helping shape the debate. Some of his recent legislative efforts include introducing the National Constitutional Carry Act, which addresses federal gun policy; the PRIME Act, which aims to reduce regulations on small-scale meat processing; and ongoing efforts to increase transparency at the Federal Reserve, often called “Audit the Fed” by libertarian groups.

Massie sets himself apart from other Republican members by challenging President Donald Trump on several of his legislative priorities. Although Trump usually has strong support from congressional Republicans, Massie has publicly broken with the president on multiple high-profile issues. 

“If you want a rubber stamp in Washington, D.C., I’m not your guy,” Massie said at an Optimist Club lunch in Crescent Springs on April 8. “I represent 750,000 people. I don’t represent the Republican Party. I don’t represent the president. I don’t work for the President. I don’t even work for the Speaker of the House. America First and Kentucky First, and that’s the way I see it, and that’s the way I’ll be.”

Massie was one of just two congressional Republicans to oppose the One Big Beautiful Bill Act in 2025, the Trump administration’s flagship legislation for that year. During the COVID-19 pandemic, Massie drew Trump’s ire by verbally opposing the CARES Act, in addition to voting against the Paycheck Protection Program and Health Care Enhancement Act and the $2.3 trillion Omnibus COVID Relief package on the grounds that it was fiscally irresponsible.

Moreover, Massie was the only Republican co-sponsor of the Epstein Files Transparency Act and publicly advocated for releasing the files. The bill was ultimately signed into law.

Outside of his congressional duties, Massie, an MIT-trained engineer, spends time on his farm in Lewis County with his wife and four children. Before entering politics, he was an entrepreneur who founded SensAble Technologies, Inc. in 1993. He sold the business in 2003.
