"I happen to be a member of the Progressive Democratic Party and I don't see many elites."
Whatever progressive values you have, ask yourself whether the Democratic Party shares those values.
If the Party did share those values, would Wasserman-Schultz and Brazile and the DNC have been caught trying to help Clinton beat Sanders?
Would Democratic leaders be consistently opposed to supporting policies like single payer and an end to fracking - policies that are immensely popular among rank and file Democrats?
If the party shared your opposition to the wars you mentioned, would Obama have started bombing Libya and Syria? Or helped the Saudis bomb Yemen? Or continued Bush's wars in Afghanistan and Iraq? Or intensified drone killing of mostly innocent people? What kind of progressive party bombs the poorest people on the planet for years on end?
Maybe we should tell the Yemenis what you're telling me - to explain why we've been underwriting the destruction of their country. "Life isn't fair, deal with it."
From where I stand it looks like the Democrats are thrilled to have your progressive money and votes - just not your progressive policies. I work happily with Indivisible and all those "outside" groups, but there is no unity to be had within the Democratic Party. Because the next Trump will be worse than this one.
