In a piece on the proposed oil sands pipeline project from Canada to Texas, the center-left Talking Points Memo picks up on an important point but doesn’t quite drive it home: “Canadians can do what they want with their oil in Canada, and there’s little American protesters can do to stop them,” notes the post.Correct. The green position is that President Obama must either kill up to 20,000 jobs to show symbolic opposition to a Canadian oil drilling plan or risk the wrath and condemnation of the mighty green movement. President Obama can’t kill the oil sands development by blocking the pipeline; he can only ensure that the US derives no benefit from the oil next door.That, presumably, is why the White House announced today that the pipeline will go ahead, greens and New York Times editorial board notwithstanding. There was no other rational choice he could make.No significant political force in the United States is as incompetently organized and led as the greens. Republicans should rejoice; green extremism, hysteria and incompetence seriously undercuts Democratic coherence and credibility. That is the point that TPM and its allies need to be making; until the rest of the left knocks some sense into green heads, the environmentalists will continue to serve as one of the Republican Party’s most helpful auxiliaries.
