Yeah, I held my nose and voted for HRC. I'm not a big fan, but she has a better grasp of the issues and isn't a "gimmick" candidate like Sanders.
Sanders is a good guy, but would have accomplished very little. Congress is not going to vote for new taxes, which he needs to fund his cradle-to-grave welfare state. Tax the rich? Not enough. Tax corporations? Still not enough. Cut spending? Nope, sooner or later middle class taxes would have to be raised and that would be the end of Sanders. As my colleague says, "Americans love free stuff until they find out how much it costs."
Estimates are that his programs would have added 15-18 trillion to the debt. No thanks.
Sanders is a big picture guy, but I'm not convinced that he would have been able to handle the day to day managerial tasks which are the less sexy side of the Presidency.
Finally, let's assume that you're right and HRC gets indicted. That's still no guarantee that Sanders gets the nomination. Delegates could just as easily go for whoever else throws their hat in the ring.
