Citing fundraising difficulties, Republican Sen. Jim Bunning, R-Ky., announced this afternoon he will not seek re-election next year. He blamed Senate GOP leaders. "Over the past year, some of the leaders of the Republican Party in the Senate have done everything in their power to dry up my fundraising. The simple fact is that I have not raised the funds necessary to run an effective campaign for the U.S. Senate. For this reason, I will not be a candidate for re-election in 2010," Bunning said in a statement. Bunning has specifically criticized Senate Minority Leader McConnell for trying to undermine his re-election plans. Bunning said he will finish out his term. GOP Kentucky Secretary of State Trey Grayson has raised more than $600,000 for a prospective campaign in case Bunning chose to retire. Physician Rand Paul, the son of Rep. Ron Paul, R-Texas, also is raising money. Democratic Attorney General Jack Conway and Lt. Gov. Daniel Mongiardo are also in the race.
