Obviously missing from the inquiry during application for a security clearance is the question “are you a Democrat?”
I recall in the late 60’s a form I had to fill out for a security clearance. The form was a full page, in fine print, names of organizations and asked if I had ever been affiliated with any of them. One organization was obviously the Communist party.
I recall my latest clearance application was dated somewhere around 2001, and that organization list form was long gone. I recall no questions asking what organizations I belonged to.
It’s my belief the Carter administration did away with it.
BTW, the outfit that required this clearance in the late 60’s also had rules, such as if you were caught in homo activities or any drug activities (it included pot), you were gone. I recall two such instances. Both persons were immediately reassigned to grunt army units in Vietnam, without first going to any AIT that qualified them for direct combat duty.
