It's real names and real doctors. Funny thing is there is a real argument he could make here but his simple mind won't make it. He could argue that the doctors signing that petition are in the pocket of Big Pharma, and he would probably be right about that. Big pharma is corrupt, does have a history of paying doctors off to look the other way. If that's the direction Don jr wanted to do. He might have even won over some people on the left.
Really for all the horrible things RFK jr will do there are some people on the left who want pharmaceutical companies to pay, and they might even give for RFK jr. Really Don Jr. Is hurting him with this.
