There is No Place for Progressives in the Democratic Party

One of the reasons that Bernie Sanders has suspended, rather then ended, his campaign, is because, as he has explicitly stated, he wants a sufficient number of delegates to be able to submit motions on Democratic Party rules.

It appears that the Democratic Party establishment (There is no Democratic Party establishment) is unwilling to even deal with concessions as minor as keeping "super-delegates" out of the first ballot, which is honestly is about the only thing that Sanders would get passed, so they canceled the New York State Democratic Presidential primary to ensure that Sanders will have insufficient votes to submit motions on party rules and the platform.

It is patently clear that the Democratic Party establishment (There is no Democratic Party establishment) sees Donald Trump as their opponent, and progressives as the enemy.

It's the Iron Law of Institutions, "The people who control institutions care first and foremost about their power within the institution rather than the power of the institution itself. Thus, they would rather the institution "fail" while they remain in power within the institution than for the institution to "succeed" if that requires them to lose power within the institution."

There is no single action more calculated to drive people who are undecided about whether to vote 3^rd party or write in Stephen Colbert (I'm leaning toward Colbert) at this moment, but they have to do it, because hippy punching is an absolute priority of the Democratic Party establishment (There is no Democratic Party establishment).
