My non-scientific survey tells me that, oddly, the more supportive people are of Obamacare the more they're freaking out about the current problems. People less inclined to love the legislation are rolling their eyes a bit but don't actually think that it dooms either the politics or the policy.
I don't think it's the end of the world, but people should lose their jobs. I don't know who is to blame, but they had a long time to implement this and they screwed it up. Occasionally people in power should take responsibility for things they're responsible for.
