It just occurred to me: If Biden wins it will send Hillary through the roof. She may have an interest in making sure a candidate arguably worse than her (Biden) doesn’t eclipse her by beating Trump.
Perhaps she will slip Hiden an extra dose of warfarin—enough to turn his pee bright red.
Hillary would suck up to any plan that enriches her, IMO, she would go along with Joe winning as she did Obama winning becasue she would be promised some money somehow.
