I think it will take at least several months for the vew forces and voices in the Democrat Party to rise up and be heard. Right now the Bernie left wing constitutes the only group still standing and not discredited by the election result
You act as though Trump won in a landslide with both the popular vote and the electoral college. Democrats aren't discredited, they simply didn't win in the swing states which affected the electoral college count and gave Trump the win. I suspect quite a few Bernie or busters decided to vote for third party or stay home and more people than anticipated in the swing states came out and voted for Trump, I suspect with their noses tightly held.
Clinton Up Almost 400K In Popular Vote
Democrats didn't win enough votes in the senate or the house, conservatives did. I am not sure what that means other than people seem to be their own worst enemies. Polls have shown (btw, the polls showed the race tightening at the end of the election, pundits just chose to disregard it for some reason) people want to go farther left on issues such as health care and college tuition cost. So I don't know why they voted for republicans who do not want those things.
