The Kentucky Supreme Court ruled Wednesday Republican Ernie Fletcher can remain on the May primary ballot. Candidate Steve Nunn's running mate -- Bob Heleringer -- challenged the legality of Fletcher's candidacy, saying the ticket was invalid when Fletcher picked an ineligible running mate, Hunter Bates. A judge ruled Bates did not meet residency requirements. But other judges ruled the Fletcher candidacy was still legal. The Kentucky Supreme Court decision Wednesday affirms those rulings. In addition to Nunn, Fletcher faces former Jefferson County judge-executive Rebecca Jackson and State Senator Virgil Moore in the May 20th primary.
