Trump just put on an absolute masterclass in this Meet the Press interview:
Welker: Do you want to see childhood vaccines eliminated?
Trump: Uh, if they’re dangerous for the children…
Welker: Studies show there is no link between vaccines and autism.
Trump: Maybe it’s not vaccines, maybe it’s chlorine in the water… I want them to look at everything.
Welker: Childhood vaccines have prevented about 4 billion deaths around the world.
Trump: That’s great. I’m not against vaccines. The polio vaccine is the greatest thing. I think certain vaccines are incredible — but maybe some aren’t. And if they aren’t, we have to find out.
