I talked with John McCain Sunday morning in the green room just before “This Week.” I asked him why he continued to call for more troops for Iraq when he must know it’s a political non-starter. He said he thought it important for the morale of the troops.

McCain gives every impression of meaning what he says, which is one of his greatest assets. But I simply can’t believe this one. What’s most important for the morale of the troops is knowing they’ll be coming home soon, not hearing some politician say we need more troops when there’s no possible chance of that happening.

I think McCain knows Iraq is out of our hands – it’s disintegrating into civil war, and by 2008 will be a bloodbath. He also knows American troops will be withdrawn. The most important political fact he knows is he has to keep a big distance between himself and Bush in order to avoid being tainted by this horrifying failure. Arguing that we need more troops effectively covers his ass. It will allow him to say, “if the President did what I urged him to do, none of this would have happened.”

McCain is smarter on this score than Dems who intend to engage in post-Baker Commission “what we must do now” bipartisanship. It may make Dems feel relevant and important, but it will also make them complicit in the impending failure. Come 2008, they will share the responsibility for the horror of Iraq. HRC will be drawn in, as will Barak Obama and all other Dem notables who will feel it necessary to participate in a “plan.”

In the end, McCain alone will be able to escape blame. At least, that’s what I think he’s thinking.
