Hillary Clinton muddied her perfectly clear statement about the science behind vaccines with a weird hashtag about grandmas.

Yech. Grandmothers know best?

I realize this tweet is more of a campaign platform than anything, but shouldn't that be #ScientistsKnowBest? My grandmothers believed in all sorts of nonsense, like that you shouldn't have hot soup and cold drinks together, but that eating raw egg in cake batter was perfectly fine.
