Obamas motivation for not approving Keystone were wholly political and motivated to reward his campaign financing benefactors.

He foisted lies, inaccuracies and false narratives that left everyone scratching their heads as to the lack of logic.  It just didn't make any sense.  Hence the "no-brainer" comment by Harper.

The US got rid of the no-brained Obama, refused to elect the hair-brained Hillary and now the comb-over is repealing one disastrous Obama policy after another.
