Fox camera swung to cover walkout for a couple seconds until someone realized this would help Trump, so the quickly swung back away from the protesters.
Ted had an embarrassed look on his face. Embarrassed that people would walk out on him. Of course he had just mocked Trump and his supporters. Ted is a sleazebag. Cruz & Beck, brothers in arms.
There were quite a few different cameras there, so I guess the one I saw on YouTube was not the Fox one. It had been edited. They took out not only the walkout but also Ted’s dismayed reaction as he stood there on the stage watching it. Maybe realizing that was originally HIS plan for Trump’s appearance and it had come back to bite him.
