Harper's no fool. He knows what Obama really is, and what his idiotic views are about the "carbon footprint" Obama thinks the oil sands make- supplying all that oil to the USA.
If Obama tries to "carbon cap" the oil America needs, there are plenty of other countries just waiting to jump into the tar pit, Japan for one, would love to expand their operations in Alberta, and are just waiting to Obama to "carbon tax" some smaller US operators out of there.
That's exactly what he's doing, and he's enlisted the aid of the opposition party's leader, that pimp Michael Ignatieff. Man, I wish Obama would go the f**k home already.
