Paul Krugman

NYT Columnist Paul Krugman

[Updated/revised: Paul Krugman has a column this a.m. discussing comments made by Obama in an interview on Fox in which Obama gave credit to Republicans for certain ideas. I usually agree with Krugman on not pushing Republican talking points, and I get the point about the role of mandates for universal health care if you're stuck in a private insurance system. But I disagree with Krugman about sharing credit on emissions trading systems, a point Krugman makes in his column today.

Krugman suggests Obama is hurting the Democratic Party by giving Republicans credit for supporting ideas like trading systems to allocate credits/allowances for emissions -- like a cap and trade program for greenhouse gases. Republicans should never be given credit, and that trading idea, we are told, emerged from Democrats during the Carter era, when his administration first sanctioned emission trading systems. Well, maybe, maybe not, but so what?

I don't know where the idea originated -- probably some academic -- but I recall we utility/energy regulators worked on this with the California Air Resources Board back in the day. They're the state agency who was assigned the task of solving the toughest air pollution problems in the country -- at least until Pittsburgh became the soot capital. Polluting industries wanted the trading flexibility, and their elected Republican allies wanted to give it to them, but it took a little persuading to get our Democratic friends to take a leap of faith and let go of the more traditional plant-by-plant limits. California then needed to persuade the feds at Carter's EPA to go along, and they eventually did.

But why criticize Obama on this point? The idea of using market mechanisms to support regulatory objectives appealed to both sides for different reasons, and it worked. And we'll need both sides to support it again; it may become, if done right, a constructive way to gain broad support for an approach that tackles part of the greenhouse emissions problem. And if Obama cites that as a decent "Republican" idea as a way of getting broader support for one of the difficult things that need to be done on global warming, it doesn't strike me as helpful to criticize the effort to build that coalition.

It's not just about getting elected; the point is to govern.
