Chris Cillizza: Bernie Sanders still doesnt know what the Democratic party stands for

[Proud Liberal Dem]

64. I appreciate what Sanders contributes to progressive causes

but I don't understand why he is so prominent in discussions about the Democratic Party, what it stands for, and how to do better in future elections when he is NOT even a member of it- and was only a member of it long enough to try to run for President last year. Why aren't people like our new DNC head, Thomas Perez, and his deputy, Keith Ellison, talked about/to more? Why aren't we hearing from people whom have been Democrats all of their lives/careers? I know that Bernie caucuses with the Democrats, I know that he votes with the Democrats almost all of the time and I get that that makes him ideologically aligned with the party but I get frustrated that it seems like, since last year, he is put up on a pedestal and given so much print and and airtime as an authority on a party of which he is not even a member- and when he spends a lot of it trying to attack the Democratic Party, oftentimes in a billigerent, non-constructive manner? It doesn't help the Democratic Party (or anybody, really) to have him continue to trash the Democratic Party and give Trumpublicans more ammo when the entire progressive/left-wing/Democratic structure should be out there fighting Trumpublicans instead of each other.
