The Jay Dardenne/Billy Nungesser race for lieutenant governor has been moving from a typical Louisiana low-blow boxing match to one of those ridiculous nighttime soap opera catfights involving evening clothes and a conveniently placed mud pit.

Dardenne and Nungesser have been sliming each other in online commercials for a while, but tonight The Battle of the YouTube moved from Baton Rouge to Hollywood, as Kevin Costner — resplendent in peacoat, beard and orange scarf — has now endorsed Nungesser. (From Copenhagen, no less.)
