Minor nit. Medicare Advantage is an optional thing people can buy into. The standard is Medicare A&B although you can also buy Medicare Supplemental (Medigap)to cover some of the deductibles (and foreign travel) and D for prescription drugs.

Totally! You caught me assuming MA given the baseline enrollment is slightly higher, and that number is also slightly greater in CA, but valid thing to note.
