It is interesting the survey authors interpret things as the public being more willing to pay more, than Congress being willing to institute change. I presume the difference is due to some having a willing indentured enslavement to Grover Norquist - guess where, public or Congress. I bet if you put Grover atop a stack sniffing flue gases for a week he might show flexibility not presently in his being. That's a thought experiment. I am not suggesting anyone do it. Yet -- as a thought experiment it rocks.
Here. Here. Norquist, himself, is an energy device.
