The Dem's have about 3 years to get a LIKEABLE candidate in position to run for POTUS.
Think they'll be able to do it or spend that time whining about losing?
Hillary will try if her health permits it. Rest of the Dem party will move on to somebody else, most likely Liz Warren (less plausible Michelle O), can't think of any 'completely fresh face' that will burst onto the national stage like another Obama comet.
They don't concern about the LIKEABLITY, they have THE MACHINE to run rough shot over us. I don't think they learned (or wish to learn) anything from the Trump victory. How they oppose Trump will tell us everything.
