Randy McNally, the longtime Republican lawmaker from Oak Ridge and leader of the Tennessee Senate since 2017, is retiring, he announced on the Senate floor. He will not seek reelection in 2026.

His retirement marks the end of a 47-year tenure in the state legislature, where he made waves for East Tennessee and rose to the second-highest ranking role in the state as lieutenant governor.

“This is a very difficult thing to do,” McNally told his colleagues Feb. 26. “I’ve decided not to run for reelection in November. My aim each day was to leave my state and my community a little better than I found them. Together, I believe we have done just that. Tennessee’s success is due in no small part to the people I have served alongside every day.”

McNally cited health concerns as the reason for his retirement, adding he wants to make the most of the coming years.

The Anderson County resident was the highest-ranking East Tennessean in the state government, elected by his colleagues to lead the State Senate and manage policy and budget priorities.

McNally, 82, represents the 5th Senate District, which includes all of Anderson and Loudon counties, as well as a sliver of Knox County stretching from downtown up to Sharp’s Ridge north to Powell and in the county’s west side through Karns and Hardin Valley.

“My public service has been a team effort every step of the way,” McNally said on social media. “I offer my deepest thanks to the constituents I have served and to the members and staff with whom I have collaborated.”

That means the Aug. 6 primary election for his seat is wide open. The general election is Nov. 3.

McNally had taken initial steps to run for reelection by pulling a nominating petition. He is the only Republican in the district to have done so.

There’s no clear successor for lieutenant governor. Top contenders include Senate Majority Leader Jack Johnson, R-Franklin, and Commerce Committee Chairman Paul Bailey, R-Sparta. The Senate Republican Caucus will hold elections to select a successor. 

Well-wishes for McNally have begun to flow.

“(McNally) has been a trusted friend and a steady conservative leader for Tennessee,” U.S. Sen. Bill Hagerty said on social media. “From his time in the House of Representatives to his service as lieutenant governor, Speaker McNally has never wavered in his commitment to the betterment of our state. Thank you for your years of service and wishing you well in your next chapter.”
