I'm shooting in the dark, but could it have been in the '80's? Boshwitz and Durenburger?
Yes, you are correct.
Durenberger and Boschwitz were both elected in 1978 in the "Minnesota Massacre".
They served together 'til 1990 when Boschwitz f**ked it up and lost to Wellstone.
I remember them. RINO Durenburger was a loser, a drunk who leaked intelligence secrets, violated Senate ethics, and had an extramarital affair with a staffer.
