If that scenario is all there is to it I would be happy. But Trump has been one of the more outspoken about vaccines and autism (maybe even more than Stein). For instance "You take this little beautiful baby and you pump ... " he said, referring to mandatory childhood vaccines. "We had so many instances, people that work for me, just the other day, 2 years old, a beautiful child, went to have the vaccine and came back and a week later got a tremendous fever, got very, very sick, now is autistic." 

He certainly has spent a lot of energy raising doubts about vaccine safety if his only goal is to placate and ignore a fringe group.
