Unfortunately "Occam's Razor" doesn't support your contention that the DD214 in question was the product of a Carter amnesty reissuance. Let's be damn careful here.
By the way, in poking around the net, I stumbled onto an exchange on this subject that you might find to be of interest...
"Did Sen John Kerry receive an Honorable Discharge from the Navy?"
Occam's razor points in that direction (IMO), as does the discussion in the link that you provided. The guy was hiding *something*, and I'm convinced that it was something more than the poor grades that he pretended it was all about when he released data to two friendly reporters.
As you can see, it's a looooong discussion, and it's very hard for me to delve back into all of that again, as I spent several months mulling over that stuff back before (and after) the election. I find it painful and unpleasant to delve into the realm of digging up dirt on a retired servicemember, even Kerry. Unless he makes more noise about running I'll leave it all lie where it's at.
But if he rears his ugly head again I'll be once again sending my money to the Swift Boat Veterans and POW's for Truth, that is, if they have the desire to yet again get themselves slandered for honor and duty.
