NASHVILLE (AP) - Democrats have nominated Mark Clayton, who raised no campaign cash, to be their candidate to face incumbent U.S. Sen. Bob Corker in November.
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.
