The Lexington Herald-Leader reports that Kentucky state Auditor Crit Luallen, who was being recruited by the Democratic Senatorial Campaign Committee, is telling party leaders that she has decided not to challenge Senate Minority Leader Mitch McConnell (R) next year. Additionally, outgoing state Attorney General Greg Stumbo, who was exploring a campaign, is now expressing a desire to return to the state legislature instead.

The news leaves Democrats without a top flight challenger to put McConnell on the defensive. Louisville attorney Andrew Horne, an Iraq veteran who lost the Democratic primary in Kentucky's Third Congressional District to now-Rep. John Yarmuth in 2006, says that he will consider running if Luallen makes her decision final.

Late Update: Luallen issued a statement today saying that she has "no plans" to enter the race.
