The DNC takes aim at John McCain's constantly shifting position on when we can leave Iraq. Some of this is unfair: of course he has changed his position on this (as Obama has), as facts and events have shifted. More salient is the resilient confusion over whether McCain would be happy to have the Iraqis ask us to leave and how soon we'd do it. I'm still unsure whether McCain would prefer to have no US troops in Iraq in ten years or not.
