This is what happened. GW secretly put his body double (his dad who colors out the gray in his hair to play the part)...into his place, and then drove a Ford Bronco up to Minnisota. There he puchased a shoulder-launched surface to air missile from Jesse Ventura, and then hid quietly in the woods. When Wellstone flew over...he fired the missile with data provided by Condi.
Yep,
That's how I figure he did it.
