My maternal grandfather who had about 3 political chromosomes dedicated to democratic principles called it right when he said Nixon should have just followed the advice given to him and 'fessed up to what he did. It would do Joe Paterno and Herman Cain good to follow the same advice.
Neither one has to completely divulge every sordid detail, merely admit some sort of culpability and fall on their symbolic sword. Joe has to leave, Herman might get to stay and make more fun happy for the D side of the aisle. I kinda hopes he does. He is siphoning off lots and lots of cash away from other candidates by his mere presence. The longer he is in the race the better it is for my man. He is an anchor now. One big massive freaking pile of iron that drags down everybody else. I personally don't give a big rat's ass if he manages to salvage his campaign or not. I kind of hope he continues on his present path.
Joe Pa on the other hand... well as much as I might despise PSU I don't really want to see his legacy so tarnished that this is the major bullet point in his bio. "Joe Paterno was asleep at the switch when his Defiendsive coordinator was butt-fucking boys in the shower"
He has to quit and like tomorrow. Tearful replies to students from his back porch notwithstanding. He has to go. Him and everybody that might even remotely have had a clue that this was happening. If PSU wants to ever and I mean fucking ever wants to get on the good side of the football gods they had better clean house and I mean now. El Presidente must fire at will and then fall on his own sword and resign. That alone will salvage their reputation and repudiate this mess. Joe can avoid the damned media a while but eventually his ego will get the better of him and his age will allow him to forget that they are still gunning for him. The PR dept will remember but he will overrule them and then he will march out there to be eaten alive. If he stays that WILL happen. He cannot avoid them forever. Sorry Joe, you gotta go. You had the power to fix this earlier and you didn't. You were the bishop in charge of this wayward priest and you just tried to hide it. That won't fly. It didn't in church and it won't on the gridiron. Your ass is grass.
Herman is toast. Joepa might be able to salvage something out of this, but it is all about ego now. Humble yourselves and admit some fault and it might go better for you. Stick to your story and it all falls down.
I personally don't give a damn if you lie your ass off.
