Mark Clayton, the winner of Thursday's Tennessee Democratic primary for Senate, has been disavowed by the Tennessee Democratic Party.

Clayton received nearly twice as many votes as any other candidate in a crowded seven-person Democratic primary for U.S. Senate, earning him the right to face popular Republican Senator Bob Corker in the fall.

Clayton has stated that he is a vice president of Public Advocate of the United States, a group condemned by the Southern Poverty Law Center as a “gay-bashing group.” On its website, the group states that it offers “strong and vocal opposition” to gay marriage and “the furtherance of so-called 'Gay Rights.'”

The Democratic Party said in a statement it would not back Clayton's campaign.

“Many Democrats in Tennessee knew nothing about any of the candidates in the race, so they voted for the person at the top of the ticket. Unfortunately, none of the other Democratic candidates were able to run the race needed to gain statewide visibility or support.”

Mother Jones reported that Clayton had a “penchant for fringe conspiracy theories,” such as national ID cards, the “NAFTA superhighway,” and accusing Google of censoring his campaign website on behalf of the Chinese government.

Democratic Party spokesman Sean Braisted recommended that “people write in a candidate.”
