Have not kept up with the Keystone Pipeline, but putting aside that Obama seems to be drawing it out pretty far, its importance at times seems more symbolic than real. The "Landrieu Gambit" seems a forgivable move given it's only a matter of time anyway and you have to throw something to outliers in the coalition at times. And, desperate people deserve a partial pass. The post there seems to suggest the symbolic messaging is essential here. Seems to me environmentalists shouldn't be impressed much with that anyway. And, she has supported the pipeline for some time; perhaps, it's a move to have one last win.
