All the evidence suggests that it has finally become politically possible to give Americans what citizens of every other advanced nation already have: guaranteed health insurance. The economics of universal health care are sound, and polls show strong public support for guaranteed care. The only thing we have to fear is fear itself. . .

The Edwards and Clinton plans as well as the slightly weaker but similar Obama plan achieve universal-or-near-universal coverage through a well-thought-out combination of insurance regulation, subsidies and public-private competition. These plans may disappoint advocates of a cleaner, simpler single-payer system. But it’s hard to see how Medicare for all could get through Congress any time in the near future, whereas Edwards-type plans offer a reasonable second best that you can actually envision being enacted by a Democratic Congress and signed by a Democratic president just two years from now. . .

There won’t be a serious Republican alternative. The health care plans of the leading Republican candidates, such as they are, are the same old, same old: they principally rely on tax breaks that go mainly to the well-off, but will supposedly conjure up the magic of the market. As Ezra Klein of The American Prospect cruelly but accurately puts it: “The Republican vision is for a world in which the sick and dying get to deduct some of the cost of health insurance that they don’t have — and can’t get — on their taxes.”
