No he isn't but remarks he has made in some of his speeches appeared to be encouraging some of his supporters to be violent. Sanders and Clinton have not done this. I think what we're seeing is a general rise in anger in this country because working-class issues have not been dealt with, have been swept under the rug. When people get too angry some of them explode. I think Sanders is giving people a constructive way to release their anger and make it have some political effect. 

The question is, what happens if Clinton gets elected and nothing changes? Which is basically what happened with Obama. For most of us, no change and no hope. Bait and switch. I didn't vote for him because I could see what was happening.
