What’s to stop Obama and “conservatives” making a deal at some point that Obama approves Keystone and the “conservatives” cave on the invasion of the US?

The Canadians should open their pocketbook and build a massive refinery. It would be worth it, since they have 200 billion barrels of proven feasible reserves.
