Kentucky's attorney General is joining the race for U.S. Senate.  Jack Conway announced he's running for the seat now held by two-term republican Jim Bunning.  Conway says he believes Kentucky needs a new generation of leadership.

He is the second major Democrat to enter the race.  Thursday, House Speaker Greg Stumbo endosed Conway. 

Lieutenant governor Daniel Mongiardo has already raised more than $420,000 for his campaign.  Mongiardo ran unsuccessfully against Bunning in 2004 - losing by some 27,000 votes.  Governor Beshear endorsed Mongiardo for a rematch last month.

Bunning has had more recent difficulties, issuing two apologies for objectional comments, including once for saying U.S. Supreme Court Justice Ruth Bader Ginsburg could die of pancreatic cancer within a year.

A lesser-known Democrat, former U.S. Customs special agent Darlene Price of Whitley City, was the first to get in the race, announcing last year that she would run.

U.S. Rep. Ben Chandler of Lexington has also expressed interest in the race as has state Auditor Crit Luallen.

State Senate President David Williams has been pondering a run and two other Republicans, Secretary of State Trey Grayson and Bowling Green eye surgeon Rand Paul, have said they would be interested if Bunning were to drop out.
