Yes, Progressives have been played for suckers - again. They had two more pies thrown in their face, courtesy of Hillary Clinton, Barack Obama, Debbie Wasserman Schultz, and all the other corporate Democrats who still control the party. Perez made an empty peace offering to Progressives, by naming Ellison as his deputy chair - a position with zero power and, we can be sure, zero influence. This was similar to Chuck Schumer naming Bernie Sanders as director of outreach, or whatever the position is called. It's the equivalent of putting someone in charge of a remote desert outpost, while all the action is going on back home.
But all of this is nothing new of course. Progressives have been punked for decades now by the anti-New Deal Democratic Party leadership and their corporate donors. Here are some of the anti-Progressive things that Corporate Democrats have voted for, caused, supported, or enabled (click on links for details):
The arrogant and elite Corporate Democrats have made a habit of rubbing the noses of Progressives in the dung of their corporate-friendly policies. Whether it's Obama backing away from the public option, or Hillary snickering at the idea of a political revolution, the democratic establishment LOVES making Progressives look like wide-eyed fools. Heck, right after Debbie Wasserman Schultz resigned from her post at the DNC, for her role in rigging the primaries, Hillary Clinton made her the "honorary chair" of her campaign. This was essentially telling Bernie Sanders and his supporters, "Ha ha, I'm hiring the woman who tilted the tables against your candidate! And you dummies are still going to vote for me because you don't have anywhere else to go. Who are you going to vote for, Trump?? Suckers!"
Here's a prediction: Donald Trump will serve two terms, and there will be a right-wing-led constitutional convention within the next few years that will fundamentally change the way we live (and not for the better, unless you're a fan of theocracy and children carrying guns) – because (a) the Democratic Establishment is owned by Corporate America, and (b) Progressives don’t have the gumption, or the organization skills, to form their own political party. With respect to the latter, there are hundreds of little Progressive protests, media organizations, think thanks, advocacy groups, etc. But they don't communicate or coordinate with each other very well (if at all), and thus end up operating like a hundred little echo chambers.
I hope I'm wrong but, with everything I'm seeing, I'm afraid my prediction will be 100% accurate.
