I think this one is dead in the water.  Ben was always the guy, to me, that was in the thick of it and managed to not get charged.  He was slick enough to run and escape that gauntlet, which is impressive, but also pretty messed up.  (He was corrupt.)  So, very talented man, he's been through the wringer and is older and wiser.  I don't think he could ever win.  I do think that, in a way, he actually would be a good governor, as he has the talent, and he is likely chastened.  But it won't ever happen.
