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.

Oh, about the voucher thing: In his debate with Vice President Biden, Mr. Ryan was actually the first one to mention vouchers, attempting to rule the term out of bounds. Indeed, it’s apparently the party line on the right that anyone using the word “voucher” to describe a health policy in which you’re given a fixed sum to apply to health insurance is a liar, not to mention a big meanie.

Among the lying liars, then, is the guy who, in 2009, described the Ryan plan as a matter of “converting Medicare into a defined contribution sort of voucher system.” Oh, wait — that was Paul Ryan himself.

And what if the vouchers — for that’s what they are — turned out not to be large enough to pay for adequate insurance? Then those who couldn’t afford to top up the vouchers sufficiently — a group that would include many, and probably most, older Americans — would be left with inadequate insurance, insurance that exposed them to severe financial hardship if they got sick, sometimes left them unable to afford crucial care, and yes, sometimes led to their early death.

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.

It’s not a pretty picture — and you can see why Mr. Romney chooses not to see it.
