There was a post some time back on FR about Bayh's father and a really sordid scandal he was supposedly involved in (I think a woman ended up dead). Of course that doesn't matter in the case of a Democrat...Teddy Kennedy is one of the party's most eminent leaders.
As I vaguely recall, it was that the senior Bayh’s wife died of breast cancer before that was so commonly discussed, People in IN will do anything for a Bayh after having defeated the Senior Bayh in 1980 in favor of D. Quayle.
