It’s not complicated. One candidate can show that he backed a winning strategy when others were tippy toeing and engaging in avoidance. Then he asserts that if elected he will get Bin Laden. The others offer no strategic thoughts at all and don’t give any impression that they care about winning. McCain’s numbers go up. What’s complicated?
It’s politics...
BTW except for Huckabee, I have seen little of “avoiding the war” or in Huck’s case dogging Bush, just more discussions on other issues, which there are many others beside the war.
Oh, except Paul, but he doesn’t count really...
