I did see it. What I can’t tell from the comments is whether these people were forced to be there. I got the impression they were employees from the venue location.
I think they were employees. Very interesting - you’d think Jeb would find some place where he could attract an enthusiastic crowd who wanted to be there .... then again, maybe he can’t do that so has to have a ‘captive’ audience. He’s tanking so badly - Trump just beats him like a rented mule so that all he can do is react and he’s visibly perturbed by it.
