The Public vs Obamacare

Jay Cost at the Horserace blog asks: Why Does the Public Oppose ObamaCare?

The impenetrability of these hyper-technical bills is a very important factor for this analysis. It means that voters must weigh their perceived costs and benefits under conditions of severe uncertainty. This point is going to affect every calculation they make.

Another problem for the bills is the Congress. It's heavy involvement has to be acknowledged as a cost, again because of the uncertainty inherent to the bills. RealClearPolitics currently shows congressional job approval at just 27%. That matters for these bills. If voters cannot evaluate the bills for themselves, they have to trust that Congress has written them well. Polls indicate clearly that most people do not trust Congress to do that. If they suspect that the bills are tailored to the special interests rather than their own, they have to factor congressional authorship into the analysis.
