I don't think it really matters, because the D party has so many problems. If they vote for Sanders, they lose the establishment and the moderates. If they vote for one of the Clinton anointed establishment drones like Biden, then they lose the anti-establishment communists and the l"libtard" "progressives. " If they vote for one of the libtard "progressives", then they lose the moderates. Trump is just trolling them, and letting them self destruct; it's funny to watch. It all actually reminds me of watching them in the 80s....all they need is the Burn in a tank ad to make the ridiculous complete...lol
