After a day in which Chris Christie and Rand Paul attracted attention for various levels of skepticism about the merits of universal vaccination of children, Hillary Clinton took the opportunity to subtweet her opponents just before 11:00 PM Eastern Time on Monday night:
The science is clear: The earth is round, the sky is blue, and #vaccineswork. Let's protect all our kids. #GrandmothersKnowBest
— Hillary Clinton (@HillaryClinton) February 3, 2015
Engagement with the post is off-the-charts, and it secured over 3,400 retweets and just as many favs in its first 15 minutes of life. This is a bit of a change of tune for Clinton, who was fuzzier on the issue back during the 2008 campaign.
