Bill Clinton has begun to walk back Obama's decision on the Keystone pipeline. Support for the pipeline is +39 among independents and +5 among Democrats. It looks as if the former president is going rogue and picking a fight with Obama and Mrs. Clinton but I'm cynical enough to believe this is just the theatrical positioning for a White House cave. There were never any serious environmental concerns about the Keystone. The greens want to make it impossible for Canada to develop its tar sands not because they opposes the open pit mining of the tar sand but simply because they don't want any new sources of energy period. The picture in the post "Ohio Shale Coalition Issues Dynamite Report on Utica Development is that of a pipeline project. In that photo the pipe looks to be about 10 inches and the Keystone will be 36 inches which only means the ditch will have to be a little wider and a little deeper. As anyone can see that is not much of an impact on any environment. Of course when the contractor has to blast through rock to cut the ditch it's a bit more involved as it is when going through forests where the right of way must be cleared but any change to the environment is very minimal.
