I am angry at liberal politicians, pundits, and constitutional experts for their hubris and narrow mindedness in not envisioning an alternative perspective.
Plenty of alternative perspectives were offered (including Canadian-style single payer, and systems modeled on various European and Asian countries' health plans) but none could pass Congress, which is not a liberal body at this time.
For my own part, I was disappointed in the healthcare law from the beginning because I too wanted single payer or possibly an extension of Medicare to cover, by increments, the rest of the people. So I'm among the small but principled percentage who are only slightly disappointed to see what's happening. The affordable care act was better than doing nothing, but it wasn't a satisfactory solution in the long run.
Quite frankly, I think the Republicans want 1) no healthcare plans at all; and 2) nothing more than to discredit Obama as much as possible. They aren't focusing at all on the needs of the people, or even pretending to do so any more.
