Clayton prevailed over six other similarly unknown candidates. With 79% of precincts reporting, Clayton had 36,422 votes, or 29%, compared with 20,267, or 16%, for his nearest challenger Gary Davis.
Clayton, a 35-year-old flooring installer, said in an interview before the election that privacy issues are his main concern, and that he thinks people are being "over-identified by the government and tracked."
In other closely-watched races, freshman U.S. Reps. Chuck Fleischmann of Chattanooga and Diane Black of Gallatin defeated challengers in hard-fought Republican races.
Four other House incumbents prevailed over challengers, while the remaining three were unopposed.
