I'm sure he sees value in poking us in the eye.
I try to look at this in light of the following questions: What does it mean to the non-enviro-nut left? What does it mean to independent voters? And more importantly, what does it mean to Democrats in the Senate that must run for reelection in 2012?
I think Dem Senators look at this and say, "oh shit, not this again, you mean now I have to face voters in town halls and attempt to back Obama up on Obamacare AND global warming?" The Democratic Party has already won its last election where they run on global warming. It's over. It's not a winning issue any more. That's why I say it is a monumental political blunder for Obama to even bring it up, it may even backfire, as the tide is swelling to repeal that which is already law.
