If there are no deferments at all, then the way to beat the system is to fail the physical and mental tests. With the internet at hand, the ways to do this will be all over the place.
But this is an entirely moot point. There won't be a draft. Not for Iraq & Afghanistan.
It would mean that Blackwater & all the private mercenary companies would be thrown out of fat, juicy contracts, so the GOP won't back it, and it's friggin involuntary servitude, so the Democrats won't either.
That would leave, like, Joe Lieberman?
