Republican State Treasurer John Kennedy and Democrat Public Service Commissioner Foster Campbell are heading to a Dec. 10 runoff to decide who wins the seat of retiring Sen. David Vitter (R).

Kennedy took 25 percent of the vote to 17.5 percent for Campbell. Because neither of them reached the 50 percent threshold in the 24-candidate field, they’re headed to a runoff.

The candidates included a handful of House representatives, a lawyer, the Public Service Commissioner, the State Treasurer and former Ku Klux Klan grand wizard David Duke, who got 3 percent of the vote.
