Tennessee Republicans didn't get a mainstream candidate on the House primary ballot in time, so the TN GOP is left with Jim Hart, who may actually be legally insane:

"Every person who opens the door -- as long as they're white -- I'll say, 'I'm James Hart. I'm running for Congress. My name will be on the ballot in the Aug. 5 Republican primary. I think white children deserve the same rights as everyone else.'"

Followup from Mike, 8/6: Even Jim Hart thought Jim Hart was too racist to become the GOP nominee: "'I didn't expect to win,' Hart said."
