Ugly, bloody scenes in San Jose as protesters attack Trump supporters outside rally
Of course the progressives are the ones violently battering, assaulting, stealing, and vandalizing, it is what they do. If they had positive policies with which to combat Trump they would use them, but they do not. And the supporters are sufficiently frustrated by this to riot, and mount violent attacks.
This will only firm the support for Trump among the middle class. This will detract from anything Clinton is saying about Trump, and it will focus attention on Trump, and away from Clinton. Sanders will also focus attention away from Clinton. The incredible shrinking woman will quickly become a non-factor in this election if she does not control the violent among her supporters.
We don't even have two candidates yet!
Why there were not sufficient police to handle this is unclear, it is not as if this could have been unexpected. Perhaps we really are at the point where progressives are simply protecting their own.
