Several long-serving Republican incumbents are nearing the end of their political careers, which could herald leadership changes. Notably, Lt. Gov. Randy McNally (R-District 5), who has served in the legislature for over 45 years, has not 100% confirmed he’ll seek another Senate termtba.org. McNally’s eventual retirement (if not in 2026 then in the near future) will open up the powerful Speaker of the Senate position. Likewise, Senator Rusty Crowe (R-District 3) is in his mid-70s and has served since 1990; any hint of his retirement could set off a scramble among GOP hopefuls for that seat. On the Democratic side, Sen. Jeff Yarbro (D-District 21), a leading Democrat, already tested the waters outside the legislature by running for Nashville Mayor in 2023. If he ever steps aside, that would be a rare open Democratic seat. Open-seat races tend to be more competitive, so if any incumbents announce plans to step down before 2026, those districts could become hotly contested in primaries and even the general. Keep an eye on announcements in late 2025: candidate filing for the 2026 primaries will close in spring 2026 (around March 10, 2026)roanecountytn.gov, so retirement decisions will likely be known by then.
