They will not go into civil war. If anything, they will breathlessly admire Hillary’s Stalinist coup.
That may be true of the party faithful, but as for the “new voters expecting change”, they may ask Obama to go indie and run a third party campaign.

I don't think so. The DemocRATic Party is a conglomeration of many special interest groups, each of them acting like two year olds. The losers will throw temper tantrums just like two year olds. I expect there to be lots of infighting. It'll be like 2000 all over again. Hussein gets the popular vote while Hitlery gets the nomination. If that happens, make some popcorn and watch the fireworks!
