I don't know why Dems with presidential aspirations don't DO something. Because hillary is delaying, there's no opposition coming forward. They'll be stuck with hillary. If the Republican Party falls victim to the usual RINO puppetmaster treachery, we'll get someone equally undesirable.
On the plus side, everyone across the political spectrum will be equally disgusted with the rigged game.
Martin O’Malley, Andrew Cuomo, Bernie Sanders. Front-runners this far out are seldom there at the end.
