Bad part about Trump is that he lives so much within his ego-sphere, that his personal anecdotes far outweigh even scientific evidence, as shown by his extreme ignorance of autism. That is a dangerous man.
Trump and Ben both deferred to "crack teams" for their policy decisions. I'm for collaborative work, but they need to, at the very least, be able to answer general debate questions.
Just to set the record straight, the reason people associate autism and vaccines is because autism typically begins to show itself during the same time period when vaccines are administered. So, a parent looking for something to blame will look to the vaccine.
