The McCain campaign just sent me a statement in which Barack Obama acknowledges that "there's no doubt that General Petraeus does not want a timetable," as though that recognition of the obvious means the jig is up. But it raises this important question: If John McCain knows nothing about the economy and most domestic issues but wants to be elected based on his foreign policy, which is apparently 'do whatever David Petraeus says,' why not have McCain do a surprise endorsement of Petraeus and drop out? It would certainly be easier than crafting a coherent foreign policy. It sounds like a campaign tactic that would be about as effective as the ideas laid out here.
