Only Strom Thurmond and Robert Byrd can be dismissed as the senator in this article, and I'm not sure about old Strom, God rest his soul.
Unfortunately, I think Kerry can be too. The articles says that when they met, "Both were ambitious, but neither was that well-known." Long before he got into politics, Kerry was very well-known as a result of his slander and activism against veterans in Vietnam. Nixon even targeted him.
