Bernie seems to be about as genuine as you can get in US politics. That said the bar has been set pretty low by criminals like the Clinton's.
Im wondering it's amazing that that evil bitch Hillary just can't keep away and feels the need to damage team members like Bernie and Tulsi.

All that tells me is those two must be proposing changes to the system that allows the oligarchy to enrich themselves at the populations expense. They also don't subscribe to the crazy left identity politics fad so in a sense they are true outsiders. maybe with the trump era and a potential Bernie era the pendulum will finally swing back.
