i'm not a fan of single payer but i would like a public option.
given how hard it was to get any change from "free market healthcare", i want obamacare to settle in for a while, improve the rough edges etc.
it would also be nice to add federal bulk purchasing at some point - to put some pressure on pharmaceuticals pricing and suchlike.
at the same time, i am glad they have a revenue model which can be used to generate new drugs. so i am not all in for cost minimisation either.
