Americans are already decided. They support the project by a wide margin, prioritizing potential economic benefits over possible environmental consequences
The problem is the American voters didn't want Obamacare but Obama thought he knew better that all those stupid people so he forced it down their throats. Now they want the Pipeline and all the jobs that come with it and again he thinks he knows better than all those same stupid people so he is going flip his finger at them and say, SORRY BUT I'M IN CHARGE AROUND HERE AS YOU ARE TOO STUPID TO KNOW WHAT IS GOOD FOR YOU. He is not going to approve the Pipeline as he wants the Green Energy sector that his DONORS are heavily invested in to be pushed down all those stupid peoples throats just like he did with Obamacare.
I expect green energy is going to go about as smooth and cost far more but he doesn't care as all he cares about is HIS AGENDA. NOT THE US TAX PAYERS
