Federal preemption isn't just for immigration

The Supreme Court justices indicated Tuesday they would throw out a huge global warming lawsuit brought by six states against coal-fired power plants in the South and Midwest. And they would do so with the support of the Obama administration.

Acting U.S. Solicitor General Neal Katyal urged the justices to end the lawsuit, insisting the problem of global warming and greenhouse gases is too big and unwieldy for a single judge to handle. It is a regulatory problem for the Environmental Protection Agency, he said.

When Arizona tried to deal with the problem of illegal immigration, all the progressives ran to court, shouting, "Federal preemption!"

I wonder how they're going to feel when that's the answer they get regarding state environmental laws.
