I never understood why the public option became the dealbreaker for so many moderates. Having a public option alongside private options strikes me as a much smaller deal than having so much government control over "private" insurance.
It didn't have anything to do with ideology....the insurance companies didn't want a public option so the "moderates" in congress turned against it. In the real world, people would have much preferred a bill with a public option than what we finally got.
Assuming that the politicians are completely controlled by insurance companies (which is a bit overblown imo), that still leaves the question as to why the companies were more concerned about a public option competitor than they were the enormity of regulation put upon themselves.
