Seven candidates are running in the Republican primary for the U.S. Senate in Alabama on May 19, 2026. Jared Hudson (R), Steve Marshall (R), and Barry Moore (R) lead in polling and media attention. Incumbent Sen. Tommy Tuberville (R) is running for governor of Alabama rather than for another term in the U.S. Senate.

President Donald Trump (R) endorsed Moore on Jan. 17, 2026. Alabama Daily News' Alex Angle wrote: "While practically every Republican candidate covets Trump's endorsement, especially in Alabama, Trump's record of endorsements in the state's Senate contest is mixed." Trump's preferred candidate in 2017 — Luther Strange (R) — lost the Republican primary, and his preferred candidate in 2020 — Tuberville — won the Republican primary. In 2022, Trump withdrew his endorsement of Mo Brooks (R) and endorsed Katie Britt (R), who won the Republican primary.

Hudson is the CEO of two organizations — the Covenant Rescue Group and The Shooting Institute. He is also a reserve deputy with the Blount County Sheriff's Office and served in the U.S. Navy. In 2022, Hudson ran for sheriff of Jefferson County. He lost to incumbent Sheriff Mark Pettway (D) 52 % to 48% in the general election.

Hudson said, "I'm running for the U.S. Senate not to join the club, but to tear it down and put regular folks back in charge. The mission is clear: lower the cost of living, keep our communities safe, and put Alabama First in Washington."

Marshall was appointed attorney general of Alabama in 2017 and served as the district attorney of Marshall County from 2001 to 2017. He previously worked as a private practice lawyer, a prosecutor, and a municipal attorney. Marshall was also a legal analyst for the Alabama House of Representatives.

Marshall said, "When we announced this campaign on May 27, we did so with a bold promise. It was based on the work that we've done as Attorney General, because I don't only just talk about those issues that matter to conservatives across Alabama, but we've been able to deliver tangible results to the people of this state, and it's that record which I am running on for the United States Senate."

Moore was elected to represent Alabama's 1st Congressional District in 2024. He previously represented Alabama's 2nd Congressional District from 2021 to 2025, and Alabama House of Representatives District 91 from 2010 to 2018. He also worked as the CEO of Barry Moore Industries and served in the Alabama National Guard.

Moore said, "I was one of the first elected officials to endorse President Trump. I believe we need more allies in the Senate who will help move his agenda forward and put Americans first. I'm the only candidate in this race with both business and legislative experience. Day one, we can go to work for the people of Alabama."

As of Feb. 10, 2026, The Cook Political Report with Amy Walter and Inside Elections with Nathan L. Gonzales rated the general election as Solid Republican. Larry J. Sabato's Crystal Ball rated it as Safe Republican.

Seth Burton (R), Morgan Murphy (R), Dale Shelton Deas Jr. (R), and Rodney Walker (R) are also running in the Republican primary.

In Alabama, a primary candidate must earn a majority of the vote to win. If no candidate wins a majority, a runoff election is held between the top two vote-getters.
