Shapiro has been anti Trump since the beginning.
His title is Editor AT LARGE, meaning he’s a freelancer. He does not speak for Breitbart.
I followed him on twitter. He began a manic anti-Trump tweet storm that was never ending and verging on Aspergers' quality pathological. I unfollowed. It seems to be a characteristic of the on line Cruz supporter. Don't know about the supporters on the street. Everybody I know is creeped out by the guy.
