Tennessee voters head to the polls Thursday in a set of primaries that could reshape the state’s political map — from the race to replace a term-limited GOP governor to a newly drawn Memphis-based U.S. House seat that prompted a veteran Democrat’s exit. The outcome will signal how strongly urban centers and rural regions are aligning ahead of the 2026 midterms.
Governor’s contest: an open field with high stakes
Republican Gov. Bill Lee cannot seek another term, and the GOP primary to succeed him has drawn high-profile figures, including a sitting U.S. senator and members of Congress and the state legislature. One Republican contender has injected tens of millions into his own bid, while the senator has drawn significant outside spending in her favor.

Tennessee primary: key races, turnout and deadlines voters need to know
The primary matters beyond party control: Tennessee has not elected a Democratic governor in two decades, so the GOP nominee is strongly favored in the fall. Still, the primary’s turnout and county-level margins will offer an early read on voter mood across the state’s population centers and rural counties.
Memphis and the new 9th District
The mapmakers’ decision to redraw Memphis into three Republican-leaning districts is the most visible change on the ballot. The shift pushed a long-serving Democratic representative to step aside, creating an open contest under the newly configured boundaries.
Among Democrats running in the reshaped 9th are state lawmakers and community activists who previously won re-election after clashes with the legislature. On the Republican side, a former state senator leads fundraising and carries the former president’s endorsement. Voters in the new district favored Trump by roughly 60% in 2024 — a dramatic swing from the previous, heavily Democratic district that backed the Democratic ticket by large margins.
U.S. Senate and statewide dynamics
Incumbent Sen. Bill Hagerty is seeking a second term and faces multiple Democratic challengers. No Democrat has won a Tennessee Senate seat since 1990, underscoring the uphill climb for the party statewide.
Three counties — Shelby (Memphis), Davidson (Nashville) and Knox (Knoxville) — will once again carry outsized influence. In recent primary cycles, the candidate who posted a landslide in one of those population centers often secured their party’s nomination by narrowly losing the other two and sweeping rural areas.
How Tennesseans are voting and what to expect on results night
Voter registration stands at about 4.7 million. Early and absentee ballots make up a majority of primary turnout in recent cycles; roughly 54–55% of primary votes in 2022 and 2024 were cast before Election Day, either in person or by mail.
- Polls close at 8 p.m. ET across the state, coordinating Eastern and Central time zones.
- In previous primaries the Associated Press began reporting results within minutes of closing and typically had near-complete counts within a few hours, though final tallies can stretch later into the night.
- As of the weekend ahead of the primary, about 397,000 Republican and 225,000 Democratic primary ballots had already been cast.
- Past primary turnout: roughly 411,000 GOP and 205,000 Democratic voters in the 2024 Senate primary; and about 494,000 GOP and 258,000 Democratic voters in the 2022 governor primary.
Counting, recounts and how winners are declared
Most counties release a large share of early and mail ballot totals in their first evening reports, which can make early-night margins look large. The official news calls come only when the calculation shows a trailing candidate cannot plausibly overcome the leader based on outstanding ballots or demonstrated counting methods.
Tennessee does not provide for automatic recounts; recounts occur only through court-ordered challenges. News organizations may declare winners even in contests subject to legal action if the margin makes reversal effectively impossible.
Who can vote in these primaries?
Unlike some states, Tennessee does not register voters by party, so any registered voter can generally choose which primary to enter. A 2023 law requires polling-place signage quoting a 1972 provision that primary voters must be “bona fide” members of the party or declare allegiance to it, language that was also added to absentee applications. The statutes do not define precisely what constitutes being a “bona fide” member.
What to watch tonight
- County-level margins in Shelby, Davidson and Knox — a big advantage in any one of these can decide a statewide primary.
- Turnout compared with early ballot totals — higher-than-expected Election Day voting could favor one party or faction over another.
- Performance in the newly drawn 9th District — results will indicate whether the GOP map changes have produced the expected partisan shift.
- Money and outside spending — which campaigns’ advertising and independent expenditures appear to have the strongest effect on voters.
With less than three months until the 2026 midterms, Thursday’s primaries offer the first substantive snapshot of how candidates and coalitions are aligning across Tennessee’s varied political landscape. Expect both fast-moving early returns from mailed and in-person absentee ballots and a slower, more granular picture as precincts report Election Day totals.
