After speaking with people close to Senator Johnny Isakson, I can confirm he has withdrawn himself from consideration for a seat on the Senate Finance Committee, open due to the resignation of Nevada Senator John Ensign. Isakson told Senate Minority Leader Mitch McConnell that because he (Isakson) serves on the Ethics Committee that investigated Ensign and is essentially repsonsible for the opening, it was neither the right time and more importantly, the right way, for him to ascend to the Finance Committee.
He’ll have another day. Probably soon. Heavy turnover is expected in the Senate after the 2012 elections.
