Yes, I agree in principle. However, the economics (well, monied interests) of it right now are not favorable. Too many people with money to make in US-Canadian trade would pull support for the politicians that push for it. That may change over time.
I think the idea was floated in the media by Mr Asshat because someone wanting the oil was interested in capturing it, but the push back from other donors was clear, and we dont hear them talking about it anymore other than to defend their "right" to float such ideas.
I see it as them showing their hand. They know they cant take the heat, so they run. Pussies.
