NASHVILLE, Tenn. (AP) -- Freshman U.S. Reps. Chuck Fleischmann of Chattanooga and Diane Black of Gallatin have prevailed in their hard-fought Republican primary campaigns.

With 88 percent of precincts reporting, Fleischmann had 27,660 votes, or 39 percent. Mayfield had 22,256, or 31 percent, and Wamp had, 19,668, or 28 percent.

Shortly after being defeated, Wamp issued a statement thanking all of his supporters and volunteers, "I wish the best to all of tonight's winners and will continue to be a voice for my generation as we move forward.”
