I have no doubt Obama has no love for Texas or Oklahoma.
As for his ideology on climate change, I think he really believes the things he says. Couple that with the face that he despises the oil and gas industry and you have a President who fights our energy independence at every turn. If it destroys our country, then all the more better.
Obama is in essence, “closing the George Washington bridge” to punish the good folks of Oklahoma and Texas by not building the pipeline.
