Keith Porter of the Stanley Foundation showed me this excellent overview of the candidates to succeed Bolton in Foreign Policy Magazine. Without revealing my favorite candidate - who would surely be doomed by my endorsement - I'll say Khalilzad has to be considered the front-runner, with Dobriansky a close second. And despite the clear legal and political obstacles, Bolton has to be considered a candidate to stay at the post. He may be willing to serve as a volunteer, and if not, does anyone really doubt this Administration's willingness to stretch the powers of the executive?
