This week brought yet more proof that John McCain's grasp of his signature issue -- the war in Iraq -- is less than firm. "I can look you in the eye and tell you [the surge] is succeeding," he told a town hall crowd. "We have drawn down to pre-surge levels." Only we haven't. There are currently 155,000 troops in Iraq; there were 130,000 before the surge. He also announced that Mosul is "quiet" -- even though earlier that day three suicide bombings rocked Mosul and a nearby town, leaving 23 dead. The day before, McCain mocked Obama for declining to accompany him on a trip to Iraq, saying: "We've got to show him the facts on the ground." Which facts are those, Senator -- the ones you're making up as you go?
