Bush is worried about AWOL NOT because of his lack of military service- even in a worst case scenerio for Bush, this will blow over before the general election (its fun to watch him squirm).
He is worried about what OTHER things from 1970-1974 are going to come out. Unlike Dean (I'm a Dean supporter!), Edwards, etc. we KNOW where Kerry (and Clark) were in 1972 and what they were doing- they were serving their country.
You have to ask:
-Anyone witness Bush using drugs? (1 pt for MJ, 2 for speed, 3 for coke).
-Any other DUIs?
-Ever slip one past the goalie? Any bastard Bushes out there? (Well- skip that last one- they're all bastards).
-Anything on tape indicating what a 'major league asshole' you are?
If AWOL can be an issue- all of the rest of this can be too.
