Wasn't Rand Beers a former roommate of either John Kerry or his brother, Cameron???
If my memory is correct, he was likely a mole himself while serving in the Reagan and Bush 41 adiministrations.
I'm terrible at research, better at wispy memories and tenuous connections. :-)
You all have found a goldmine of info here.
BTW, if Mary is from northern Ohio, Michigan State is hardly a far away university for undergrad work. And McCarthy is a common name in that area. I went to high school with a few of them...

I don't recall any mention of Beers in the role of roommate, but heck, I didn't pay close attention to Kerry's campaign workers.
