The Latest on Tennessee's primary elections (all times local):
The polls have closed for Tennessee's primary elections.
Turnout was light with no contested statewide candidates on the ballot and scorching temperatures baking most of the state.
A crowded field of candidates was vying for the Republican nomination in the state's 8th Congressional District, where Rep. Steven Fincher is retiring after three terms.
Incumbent Reps. Diane Black of Gallatin and Scott DesJarlais of South Pittsburg also faced tough Republican primary challenges. GOP Reps. Chuck Fleishmann of Chattanooga and Phil Roe of Kingsport and Democratic Rep. Steve Cohen of Memphis faced less active primary challengers.
Meanwhile, Democratic Rep. Jim Cooper of Nashville and Republican Reps. John J. "Jimmy" Duncan Jr. of Knoxville and Marsha Blackburn of Brentwood had no primary opponents.
Voting has been light amid the scorching heat in West Tennessee for the Republican primary to succeed retiring U.S. Rep. Steve Fincher.
The candidates who have spent the heaviest on the race for the GOP nomination for the 8th District seat include radio station owner George Flinn, businessman Brad Greer, state Sen. Brian Kelsey, former U.S. Attorney David Kustoff and Shelby County Mayor Mark Luttrell.
In Fayette County on the outskirts of Memphis, former Kustoff's bid resonated with retired commercial pilot Roy Neuhauser of Oakland because of role in prosecuting former Democratic state Sen. John Ford following the FBI's Tennessee Waltz corruption sting in 2005.
Systems analyst Don Turner of Eads said he was persuaded by former Arkansas Gov. Mike Huckabee campaigning in support of Kustoff.
Rutherford County voter Steve Helton says he's in favor of replacing incumbents this Election Day.
The 62-year-old who was casting his ballot in Christiana on Thursday said, "We need to get rid of every one of those bastards in Washington, D.C. They've got to go."
Campaign workers are outnumbering voters at several polling locations in Rutherford County with light turnout despite sunny Election Day weather.
Helton, who owns his own transportation business, said he voted for Grant Starrett in the GOP primary in the 4th congressional district, hoping to oust incumbent Republican Rep. Scott DesJarlais.
Joseph Clara, a 47-year-old construction project manager, said he normally would have voted against the incumbent but voted for DesJarlais because Starrett is from California.
"He has no roots here," Clara said.
