Krugman is even sharper than usual today:
How many deaths are we talking about? That’s not an easy question to answer, and conservatives love to cite the handful of studies that fail to find clear evidence that insurance saves lives. The overwhelming evidence, however, is that insurance is indeed a lifesaver, and lack of insurance a killer. For example, states that expand their Medicaid coverage, and hence provide health insurance to more people, consistently show a significant drop in mortality compared with neighboring states that don’t expand coverage.
[…] So there’s no real question that lack of insurance is responsible for thousands, and probably tens of thousands, of excess deaths of Americans each year. But that’s not a fact Mr. Romney wants to admit, because he and his running mate want to repeal Obamacare and slash funding for Medicaid — actions that would take insurance away from some 45 million nonelderly Americans, causing thousands of people to suffer premature death. And their longer-term plans to convert Medicare into Vouchercare would deprive many seniors of adequate coverage, too, leading to still more unnecessary mortality.
[…] So let’s be brutally honest here. The Romney-Ryan position on health care is that many millions of Americans must be denied health insurance, and millions more deprived of the security Medicare now provides, in order to save money. At the same time, of course, Mr. Romney and Mr. Ryan are proposing trillions of dollars in tax cuts for the wealthy. So a literal description of their plan is that they want to expose many Americans to financial insecurity, and let some of them die, so that a handful of already wealthy people can have a higher after-tax income.
