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.
The MACHINE is likely to find that some sand has been tossed into it’s crankcase...
