Nobody believes that either the goons or greens would vote for any republican for POTUS, but the question is how much "enthusiasm" is at stake WRT get-out-the vote workers and contributions. So which one would be worsa for Obama to p*ss off? Union members sre forced to "contribute" via dues. Maybe they got a bunch of threatening letters from greenies and took them seriously.
I agree totally, what he is doing here will manifest itself in lack of turnout in Nov. 2012.
I also believe the story of the election will be how blacks did not turn out. They are increasingly embarrassed by him. Not many will say it right now, that is, turn on him in a public way, but the lack of enthusiasm is there. Even this issue, the suppression of the pipeline and the offshore drilling, has a black constituency component, in that green issues simply aren't on black citizens' radar. They instinctively make the connection however, when they go to the pump.
You can bet that the Republican candidate will do a lackluster (at best) job of using this as a political club next year. The GOP seems incapable of or unwilling to play hardball with these leftwing crackpots.
The rats are proposing economic suicide for everyone working in traditional carbon sources of energy, not to mention those that are fracking for natural gas. IMHO, this could be the end for the Jacksonian Democrats and the rest of the rats.
