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.

Unfortunately, there’s a lot of that around.

True, one kind of fear seems, provisionally, to have been overcome: the timidity of Democratic politicians scarred by the failure of the original Clinton health plan.

To see how much things have changed, consider Hillary Clinton’s evolution. Just 15 months ago, The New York Times reported that “her plans to expand coverage are tempered and incremental,” and that “she continues to shy from the ultimate challenge: describing what a comprehensive Democratic health care plan would look like.”

Indeed, when she was asked how costs might be controlled, she demurred: “It depends on what kind of system you’re devising. And that’s still not at all clear to me, what the body politic will bear.”
