The Democratic Party is going to take a big step to the left. About time, and it's only fair, given that the Republican Party has moved pretty far to the right recently.
Idk, I'm finding it hard you're going to see a national shift to the left within the party when you have so much resistance from the Clinton people who control it right now. The fact they aren't even willing to make a symbolic gesture to "Bernie-crats" by nominating Keith Ellison as DNC chair shows how much disdain they have for this brand-new coalition.
The Goldwater-Reaganites didn't overtake the Nixon-Ford coalition overnight either ya' know.
