Well, yeah, sorta -- but he did "hold office" in the U. S. government. That's why he was called an Army OFFICER.
So to find a POTUS who never held any kind of public office, we gotta go all the way back to Woodrow Wilson -- truly one of the worst men ever to wear the Presidential mantle.
Much as I like Cain, he ain’t no IKE. Being the Supreme Commander of hlaf the world is a LOT of experience.
He sure as hell ain’t no wilson, than God. Nobama is wilson.
See my point? Too big a hill.
