This is great, and it's a big chunk of population, but I keep feeling like we could do better. For example, these three States could do a great job, but there's nothing stopping a bunch of the other States from bungling it (like, say, ignoring health experts and exempting certain groups from mass gathering restrictions). Then those States end up exporting infectious individuals into the States which are doing things right, and creating more clusters.
If only we had some sort of united group of all the States, where the response could be coordinated and centralized for maximum effectiveness.
