The Democrats painted themselves into a corner when they became the Corporate Bitch party under Bill Clinton.
Now that they have been caught so plainly betraying the people of their party, they can expect campaign donations from individuals to greatly dwindle. In other words the DNC's only move is to go "all-in" as the Corporate Bitch party. I'm talking about actions here not words. They will continue to pretend to be pro-worker, but what their elected representatives vote for will continue to not be. Past the point of no return.
If the Democrats are to really try to fix their problem, there is a good chance that they will become a 3rd party behind either the Green's or the Libertarians, because they just wont have the money to win elections any more. You can forget about any real grass roots, although they might pretend once in awhile. It will be a losing fight to retain the seats that they have, with no shot at all for them to be taking any new ones, for years.
The remaining established Democrats are not going to go down without a fight. Here "going down" doesnt mean losing to Republicans, it means being voted out by their own party members. They will continue to take every corporate dollar they can because the other options is going away.
In an ideal world the betrayers would just go away and let the party fix itself as quickly as it can... but thats not going to happen. Expect them to get even dirtier towards actual progressives. Even more corrupt towards actual progressives.
I myself am mostly conservative I guess, but not a Republican. I believe in liberty and small government, but most of all I believe that voting for the lesser of two evils is still supporting evil. I voted for Gary Johnson because ever argument against him was speculation (FUD) about what he would do in the future with not a single reasoned argument against him about anything that he ever did in the past. I know for certain that Hillary and Donald are both fucking evil.
