All politicians, including Bernie must cater to the rich and wealthy. It's our jobs as voters to discern the true reason why they do it. It's a cruel reality that without the support of the wealthy, no one will make it to congress to effect change. Every successful politician knows this very well. They know not to bite the hand that feeds, so each one (*that works for progress and not personal gain) must walk a very thin line to effect that change while also making sure they aren't removed from office for fear that whatever they did could quickly be undone.

Bernie is in it for the right reasons. Biden and Clinton were in it for the right reasons. Having personally interacted with a few politicians in private settings (no cameras or hidden recorders) I can say that even some Republicans are in it for the right reasons, but differ in ideology and how to effect that change. In the end they play a fictional role when tv cameras are around.

Personally, I was most impressed by my interactions with Marco Rubio of all people. He's exceptionally bright, and cares very deeply about the protection of this country, and it's a very good thing he is vice chairman (or chairman during Republican senates) of the Senate Intelligence Committee as it seems to be his calling. It's just unfortunate that in front of the cameras, he needs to dumb himself down in order to get elected by Republican voters.
