Businessman Weston Wamp, a Republican, announced Monday that he will challenge two-term Rep. Chuck Fleischmann, R-Tenn., for a second time.

“America is too great for this Congress to continue to divide our nation and avoid their responsibilities,” Wamp said in a release. “I want to give the Third District an independent conservative voice and a reason to believe our government can still work and serve the people.”

Wamp, the son of former Rep. Zach Wamp, R-Tenn., challenged Fleischmann in 2012. He came in third in a three-way primary against Fleischmann and dairy magnate Scottie Mayfield.

During his 2012 bid, Wamp proved to be an adept fundraiser. He raised nearly $645,000 for his challenge. He spent some of that on a unique television ad, which raised eyebrows in the Volunteer State.

Wamp ended the 2012 race with an empty war chest, according to documents filed with the Federal Election Commission.

The Tennessee primary is Aug. 7.

Tennessee’s 3rd District is rated a Safe Republican contest. GOP presidential nominee Mitt Romney carried the district with 63 percent in 2012.
