See my other comments; it is not possible for RFK to have had any effect on this outbreak. If everyone getting measles was 2 or under, it could be possible; they aren't.

The reason I bring up Canada is as counterevidence; if it was Trump or RFK'S fault, Canada should be doing just fine. They had twice the cases last year in 1/10 the population. The truth is this is a problem with people believing stupid things, and it's going to take a lot more than Trump going out of office to fix.
