WHO: Democratic congressional candidate Nikki Tinker.
WHAT: The challenger released a television ad linking incumbent Democrat Steve Cohen with the KKK for voting against renaming a park in Memphis.
WHY IT’S DIM: Cohen, who has represented Tennessee’s 9th District since 2007, tried to join the Congressional Black Caucus and endorse Barack Obama early in the primary season. Trying to call him racist is just foolish.
CURE: Ignore the racial politics being played.
