Actually, I believe that consenting acts between adults are the business of the adults and their spouses. In the case of Cain, his wife has known what he really is for probably 38 of their 42 years of marriage. She's made her choice just as other men and women make their choices about their cheating spouses.
Repubs will let any low-life scum back into the fold - even those who refuse to support their children, such as Newt who left his children with his very sick wife and without heat or food or the screaming-out-of-control bagger, Walsh who says he can't pay his back child support because he only makes $175K a year. They turn a blind eye to scum who break the law - Coburn and Ensign - and pretend nothing happened.
Libs, otoh, cast out the wrong doer even if he really never did anything more than fantasize about it with another CONSENTING adult, such as the case of Anthony Weiner.
Most disgusting to me is that these holier-than-thou, "family values" yahoos just go right on telling the rest of us how we should live. All the time the pubs and bags are preaching their family values to us and telling us they are "for" smaller government and personal responsibility, they're sneaking around with the laws to stop basic freedoms and refuse to take responsibility for their damn health care costs.
Yeah, I know - we tax payers pay for the very health care plans the congress refuses to let us have. Same old Repubs - Let Them Eat Cake, We Got Ours and We Don't Work For The 99%, We Work For The Koch's.
Cain shouldn't be running for any office. Not because he's a philanderer but because he's not qualified to be anything but what he is - a failed and fired business man, failed and fired lobbyist, ignorant of the world, can't even read a newspaper because its longer than his required 3 pages, smarmy radio entertainer. And, for Pete's sake, the fool LIES about his escapades even before they make the news!
The worst is that he does all this while he's some kind of deacon in his church. Same with church-going Newt.
