Twice now the Dish has written that "the McCain and Obama positions on Iraq will be as minimal as McCain can make them by November." I simply don't understand how that could be politically tenable for McCain. Obama is favored by something like 30 points on the economy and 20 on domestic issues more generally. Iraq and foreign affairs more generally are the only issues McCain can feasibly run on. If he moves towards Obama he will cut his own legs out from under him. Maliki has more or less done that already, putting McCain in a very awkward position. But moving towards Obama on Iraq would take away one of the few contrasts that could possibly be favorable to McCain. How does he avoid an overwhelming landslide if he can't keep both sharp contrasts and focus on the Iraq issue?
