Pressed to say what Republicans might do to help the 30 million people that the Affordable Care Act is expected to provide with health insurance, should they actually repeal the bill, Sen. Mitch McConnell said, "That's not the issue."
And if you follow what he, Mitt Romney, and other Republicans have said about health care over the past two years, you see that this is no aberration. They don't think that people without health insurance is or ought to be a political issue.
The various Democratic approaches to health care reform all assume that the government should be helping all Americans to get health insurance, so they can get the care they need. (And so the burden of caring for sick people is shared more equitably.)
Republicans do not agree. They think the government's job is only to do such tinkering as might help the health insurance marketplace work more smoothly, and then get out of the way. Whether poor people get health care, they argue, is not the government's problem. People without health insurance should work harder, save money, and buy their own plans. That this is effectively impossible for people with pre-existing conditions is not the government's problem either; those people, I guess, should get the sort of jobs that provide care to all employees.
So there you have it. If you think all Americans should be able to get health insurance, even the poor and sick, vote Obama. If you think that is not the government's business, and whether people get health care ought to be up to them, vote Romney.
