Jimmy Carter accusing an Administration of incompetence in foreign policy is like…
(a) … John Kerry saying somebody looks dorky in their pictures.
(b) … Bill Clinton pontificating about marital fidelity.
(c) … John “40% contingency fee” Edwards griping about executive pay.
(d) … Ted Kennedy hosting a double-header fundraiser for MADD and free swimming lessons for the overprivileged.
