Kentucky Sen. Jim Bunning (R), who announced his intention to retire earlier this week, has shut down his political action committee, according to a filing with the Federal Election Commission.The move by Bunning — who accused some Senate Republican leaders of trying to sabotage his re-election efforts before bowing out of the race — is a signal that the irascible Senator has little interest in trying to help his party financially this cycle as he heads out the door.However, Bunning’s campaign account still has almost $600,000, which he could distribute to Republicans.Bunning, a Major League Baseball Hall of Famer, formed his Political Hall of Fame PAC in 2004. The committee’s most active year came in 2006 when he shelled out about $190,000 in disbursements.According to Bunning’s termination report, the Political Hall of Fame PAC spent a little more than $15,000 in the first six months of 2009 and Bunning made just two donations from the PAC this year. The first was to the Republican Party of Kentucky in March for $800. The PAC’s other contribution came on June 30, when Bunning zeroed out his leadership committee with a $4,049.98 donation to the campaign committee of Rep. Geoff Davis (R-Ky.), who holds Bunning’s old House seat.
