well, the republicans and john mccain specifically is trying desperately to get away from the reality of john mccain's position which is that he has a plan for staying in iraq and barack obama has a plan forgetting out of iraq. barack obama has a plan for ending the war. john mccain has a plan for continuing the war. he has said so very clearly dozens and dozens of times. what the mccain campaign is trying to do is take the normal statement of anybody smart enough to be president of the united states and ready to be president who says he'll may refine tactically what you might decide to do over the course of that withdrawal and how you protect american troops and how you, in fact, get the iraqi army to stand up faster. but it is no change whatsoever in his fundamental determination to end the war. john mccain, on the other hand, has proven he's been wrong about every judgment he's made about the war. wrong about the iraqis paying for the reconstruction, wrong about whether or not the oil would pay for it, wrong about sunni and shia violence through the years, wrong about the willingness of the iraqis to stand up for themselves. wrong even now in his own judgment about time lines, et cetera, which he's now changed. bob, the bottom line is they're trying very hard to make an issue where there really isn't one and where the contrast could not be more forceful.
