An 80 year old wouldn't be on Obamacare proper, he or she would have Medicaid (Part A and B) as their primary and possibly another insurance as a gap filler, I'm guessing in McCain's case it's most likely Tricare from his military service and/or whatever he gets as a Senator (GEHA?) so he might actually have a secondary and a tertiary. Needless to say he will be paying little to nothing out of pocket.

Whoops - Medicaid = Medicare
