AP News Guide: A look at Tennessee's Aug. 6 primary races

NASHVILLE, Tenn. (AP) — The heated race to become the Republican nominee for an open U.S. Senate seat tops Tennessee's primary election Thursday, as well as contested challenges in a handful of U.S. House and legislative seats. Here is a summary of those offices on the ballot:

View all (3)

U.S. Senate

Republicans

Former U.S. Ambassador to Japan Bill Hagerty, 60, and trauma surgeon Manny Sethi, 42, have emerged as the top contenders for the seat being vacated by outgoing Republican Sen. Lamar Alexander. President Donald Trump has thrown his support behind Hagerty, who has contended that Sethi wasn't a good enough advocate for Trump during the 2016 election. Sethi has countered by describing himself as a conservative "outsider" and criticizing Hagerty as a part of the “political establishment.”

Democrats

Nashville attorney and former Army helicopter pilot James Mackler, 46, is the leading hopeful for the seat. If he wins the primary, it's expected to be a challenge, considering Republicans have held both of Tennessee's Senate seats since 1994.

___

1st Congressional District

Republicans

Sixteen GOP hopefuls are crowding the ballot after U.S. Rep. Phil Roe announced earlier this year that he would retire. Top candidates include longtime state Sen. Rusty Crowe; state Reps. Timothy Hill and David Hawk; and Diana Harshbarger, a pharmacist from Kingsport running for political office for the first time. Two previous mayors are also running: former Kingsport Mayor John Clark and former Johnson City Mayor Steve Darden.

Democrats

Blair Walsingham is the only active candidate campaigning for the seat in the primary. Walsingham is a U.S. Air Force veteran who has been endorsed by former presidential candidate Andrew Yang.

___

5th Congressional District

Republicans

No active Republicans are running for this seat.

Democrats

Incumbent U.S. Rep. Jim Cooper, a white lawmaker with a reputation as a moderate Democrat, is up against Keeda Haynes, a Black public defender, in the primary for just one of two Democratic-held congressional seats in Tennessee. Haynes argues that the Middle Tennessee district should be represented by someone more progressive, while Cooper has countered that he has voted overwhelmingly with Democrats during his long political tenure. Cooper has held his Nashville-area House seat since 2003. Before that, he served in the House representing the 4th Congressional District from 1983 to 1995. Joshua Rawlings is also running in the Democratic primary, but he has raised the least amount of money out of the three.

___

8th Congressional District

Republicans

Two-term incumbent David Kustoff is running unopposed in the GOP primary.

Democrats

Four candidates are vying for the Democratic nomination in the Republican-leaning district, though only Erika Stotts-Pearson has filed a campaign finance report.

___

9th Congressional District

Democrats

A vocal critic of President Donald Trump, seven-term incumbent Rep. Steve Cohen faces former Shelby County Democratic Party chair Corey Strong in the primary in the 9th district, which includes majority-black Memphis. Cohen, who is white, has won his past six general elections by 74% of the vote or more. Strong, who is Black, is a U.S. Navy veteran vying for an upset.

Republicans

Charlotte Bergmann is running unopposed on the Republican side. She has lost three previous general elections to Cohen in the 9th district.

___

Statehouse

In the GOP supermajority General Assembly, all 99 state House seats and about half of the 33 Senate seats are on the ballot.

Republican Sens. John Stevens, Paul Rose and Bill Powers, and Democrat Sen. Sara Kyle face primary challenges.

Moderate Republican Sen. Steve Dickerson of Nashville will find out which Democrat he will face in November: Kimi Abernathy, who has an educational counseling practice; or Oak Hill Mayor Heidi Campbell.

Two former state commissioners are facing off for the Republican nomination for retiring GOP Sen. Dolores Gresham’s seat: Jai Templeton, who led the Department of Agriculture, and Page Walley, who headed the Department of Children’s Services. One Democrat is unopposed.

In the state House, there are contested GOP primaries for the seats of Republican Reps. Timothy Hill, Bill Dunn, Martin Daniel, Jim Coley and Andy Holt, who are all leaving at the end of the term. Coley's seat also features a Democratic contest. Additionally, there's a contested Democratic primary for the seat of Rep. John DeBerry, who was kicked off the Democratic ballot but has indicated he wants to run as an independent.

The House also includes more than a dozen contested primaries for sitting Republican lawmakers and nine for Democratic incumbents. One is Republican Rep. David Byrd, who has faced allegations by three women of sexual misconduct that stem from three decades ago when he was a high school teacher and their basketball coach. He has two Republican challengers.

Byrd cruised to reelection in 2018 after the sexual misconduct allegations were made public earlier that year in his conservative-tilted district.

Byrd has not outright denied the allegations, though he has said he’s sorry if he hurt or emotionally upset any of his students. He was never charged.
