Scottie Mayfield says they're comin' after him!

"Republican leaders and voters report that we'll be attacked on TV soon," the Athens, Tenn., dairy executive wrote on Twitter. "False/negative ads have no place in [Tennessee's 3rd Congressional District Republican] primary."

Joe Hendrix, a spokesman for Mayfield, said, "Scottie committed to not going negative in any way." He declined further elaboration on that basis but said his boss anticipates attack ads with "fabricated" content.

U.S. Rep. Chuck Fleischmann, the well-financed, first-term incumbent Mayfield is trying to unseat, denied having knowledge of anything Mayfield implied.
