I find it hard to know what's in her mind, Bob. On the one hand seems to be much the antithesis if a sellout, but the stumping for Hillary confuses. Maybe she thinks that with Hillary getting elected, there's the much better chance of her accomplishing what she believes in for the little guy, a means to an end. I think she used to be a republican then switched. Warren sure seems smart enough to know the game that Hillary plays, and not approve of it. Being a Trump hater would help to sway her as well.
I would imagine that a person that really believes in and wants to participate in responsible government, would find it a challenge to work through the maze. Compromises could be a part of it, smiling when you feel like crying.
