For Bernie to have any effect, the whole of Congress would have to change was well. There are not that many seats there that will change - even if the Dems scored a landslide. Social change is going to come in increments - if a Democrat wins - assuming Hillary.

Hillary if elected will keep the Supreme Court sane. That matters. So does maintaining other policies already in effect.
