Andrew Sullivan wrote this excellent opinion piece for the London Sunday Times that lays out the case why John McCain is the only Republican who can end the Iraq war with honor and dignity.

McCain, however, looks better not just because he has stuck to his pro-war position while acknowledging painful reality, but because the others have increasingly looked so unnerving. Romney’s plastic demeanour and say-anything style have not caught on outside the first two states where he has poured millions of his own money into blanket television advertising. Thompson has yet to seem a viable president. Giuliani’s bizarre personal quirks and all-purpose, random hawkishness do not calm nerves in a very unstable world. Fellow Republican candidate Mike Huckabee is a jovial inheritor of Bush’s spend-like-Jesus conservatism, but has zero foreign policy experience. And so . . . we come back to McCain.
