When the difference was between McCain's "stay 100 years if necessary" and Obama's "timetable," I preferred Obama's position. In the interim, Obama slid and started saying that he'd trust his commanders and leave when stability allowed or some mealy-mouthed thing. But now that there is a rough timetable and the Iraqis want us out, both candidates have about the same position: leave when the Iraqis ask us to. That's about 2010, which is fine with me. Since there's little difference in the candidate's position now, it's not a convincing issue for me.
