NUmber one difference. MassCare didn’t effect my health insurance one bit, because I live in a different state. MassCare was inflicted by it’s own citizenry upon themselves, through their own liberal state legislature.
Obamacare was inflicted by mostly liberal senators on the entire country, regardless of whether we supported them or it.
I’m all for allowing each state to try their own way of “fixing” health care, and if a few screw themselves up in the process, we’ll all learn something.
