This circus is going to be going on a very long time. It's called death by a thousand cuts. Obama will drag this out for as long as he can, it would not surprize me if it gets passed on to the next President. He is putting on the appearance of a deliberate process here, but behind the scences they are cooking up a ideas designed to put this off as long as they can. It is a successful strategy in that they are seeing a number of oil development projects cancelled or postponed. The lack of alternatives to get the oil to other markets is working in their favor as well. As time goes by the costs of these oil and pipeline projects just keeps going up which makes alternatives that much more competitive. What amazes me is that Canada just plays along with this charade.
