[Wisconsin Dem. Sen. Russ] Feingold: No health care bill before Christmas

Feingold also said he has not been a supporter of so-called cap-and-trade proposals, and he compared the issue to global warming, at least with respect to gaining cooperation from other nations.

"You know, the other countries won't play ball," he said of his attempts to get the international community to work together on global warming. "Maybe we should impose tariffs. We should put some pressure on them. They cannot be given a free pass, and we cannot do cap-and-trade alone."

Feingold said his lack of support for cap-and-trade and his votes to cut spending have sometimes put him at odds with the Obama administration.

"There's a survey that shows that I am the Democrat who has least voted with President Obama," he said.

I find it interesting that Rajendra Pachauri the head of the IPCC is referred to as the top UN climate scientist . If an economist can be a climate scientist can I be one too? I have a thermometer.
