I don't think he cares. I'm not even sure he'll run again, he's getting up there in years. He's bought and paid for. Corrupt through and through. Only thing that'll change his mind is his pocket book, and his pocket book is being filled by the same people who are filling right wing pocket books. It's all there to see in his campaign funding. There is a reason he went into the senate 10 years ago 100% against the filibuster and is now 100% all in on the filibuster. Corruption. simple as.
