Editor's Note: After looking at the economic platform of Mitt Romney’s presidential campaign, this installment of our series on his policy plans examines the details of his health care agenda.

The gist: Repeal the Affordable Care Act; end Medicare and Medicaid as we know it, by turning the former into a voucher program and the latter into a block grant scheme; unravel private insurance, by changing the tax treatment of benefits and undermining state regulation.

The good. Not much. Once in a while he talks up worthwhile reforms designed to improve the quality of care. He also endorses malpractice reform, which is a worthy idea, although his approach would do in a way that reduced damage awards without improving compensation for actual medical errors.

The bad: Changing the tax treatment of health insurance makes sense if you do it alongside other reforms. But if you do it without those reforms, it undermines employer-sponsored coverage without providing adequate alternatives.

The ugly: Tens of millions of people would likely end up without health insurance, relative to what will happen if current law stays in place; in fact, the number could reach 58 million, according to one credible estimate drawn from the (admittedly vague) things he's said so far.
