Let's be clear what the real agenda is here.
It's UNITY, being INDIVISIBLE, COMING TOGETHER, or some other euphemism.
No matter how much Perez echoes Sanders on this "Come Together" Tour or how much Sanders spouts this is to adopt a progressive platform, the very name of the tour gives away what it's about.
It's about Berniecrats and other progressives in the Democratic Party 'uniting' to support the establishment Democrats in 2018. It's about cutting out any challenges from the left in the primaries before they can even begin.
Oh, they'll let Bernie's people work to run their kind in races already owned by the GOP with little chance of flipping. But they are doing their damnest right now to make any idea of primarying a Neo-Con, Neo-Liberal, corrupt, Wall Street owned sitting Democrat totally verboten, unthinkable, an act of 'not fighting Trump.'
The party will not move left, no matter what these folk say on tours, unless there is revolt in the party in primaries, not 'unity.' Until that happens I won't even begin to consider returning to the fold.
