Purposely Obtuse Establishment Democrat Or Just An Asshole?

Is it odd that establishment Dem-types are always shitting on anyone in their party approaching center-left?  No, of course not.  The Dem presidents since the 60s have been very far right: Carter, Clinton, Obama--not a leftie or center-leftie among 'em.  But that's the same old point: single payer health care, universal health care, moderate centrist policies are not priorities for the Democratic Party and never have been.  The Democratic Party establishment is a rock-ribbed conservative party and always has been.  Yes, at times the Dems have been more sane, pragmatic, successful, useful than the loathsome Republicans, but never has the Democratic Party been anything approaching left or liberal or whatever, so things like Single Payer have never been priority.  For Bernie Sanders, who is a boring centrist, things like universal health care matter, but he knows the party and the nation need to start somewhere.  That somewhere is with Sanders or it is not at all in 2016.  Odd that a purported health care "expert" is so enamored by with the existing Democratic establishment?  No, of course not.
