Right-wing Americans have finally exposed the true extent of their scientifically and socially illiterate barminess.
...which is radically at odds with the fact that opposition to vaccination is heavily concentrated in liberal areas. As a CDC official said a couple of days ago, if you want to find unvaccinated children, put a pin in each Whole Foods store on a map and draw a one-mile radius around each of them. The state with the highest rate of kindergartner vaccination in the US is not California or Massachusetts but Mississippi. I can only begin to list all the Democrat politicians and liberal celebrities who are either antivax or have flirted with antivax pseudoscience, starting with Obama and Hillary Clinton, we have Bill Maher, Kristin Cavalieri, Jim Carrey, Mayim Bialik, Charlie Sheen and Robert F Kennedy Jr. (to whom John Stewart gave a sympathetic Daily Show interview in 2005).
Republicans, being these days largely of a libertarian bent, often support in principle parents' right not to vaccinate their kids, but statistics show they tend to vaccinate their own kids. A map of of non-medical vaccine exemptions, produced by the far-left Mother Jones, shows an excellent correlation with those states that vote left, particularly granola states (those inhabited by 'flakes fruits and nuts') such as Oregon and Vermont. Meanwhile, the non-blue state parts of the Midwest, and the South, vaccinate religiously, so to speak.
