As far as I can see, RomneyCare’s “working” within the meaning of the polling question must largely be a function of public perceptions respecting its success in achieving something close to universal health care coverage and in slowing the rate of inflation in the health care market. According to this analysis from FactCheck.org, RomneyCare has certainly met expectations on the coverage front and has arguably met them on the cost front. Yet a near-majority of registered voters in a sample in which there are three Democrats for every Republicans still think RomneyCare's not working. Presumably there’d be an even higher level of dissatisfaction among a representative sample of likely voters.“Massachusetts health care was seen as working by 38 percent of registered voters, while just under half (49 percent) said it is not working, and 13 percent were undecided. Asked if Mitt Romney’s role in health care here would help or hurt his presidential campaign, 54 percent of voters said it would hurt; 22 percent felt it would help; and 22 percent were undecided.”
That has two sobering implications for national Democrats who'll have to defend ObamaCare in the next election: first, people who have health insurance may not care nearly as much about universal coverage as Democrats thought; and second, even if ObamaCare succeeds in “bending the health care cost curve,” voters aren’t likely to notice.
