If you believe the media hype, he was battling stage 4 cancer and having multiple affairs with bizarre women, one of whom (at least) was engaged in a lesbian affair at the time.

hey...Cain just publically admitted that he did in fact give this latest woman scads of cash on multiple occasions without his wife knowing anything about it...not so much media hype...more a real douche bag!
