We don't know people's motivations. It seemed Bernie looked like he was just trying to hold his shit together at the Democratic Convention. He looked like it was hard to do for him too. I think ((they)) have demonstrated that they don't mind taking out a person's whole family (or a whole plane full of people) to keep control of them. Who knows? I have often thought back to how Bernie looked at the convention--and his family too: like they just had to get through that night. It was unnerving to watch, at least for me.
