Obama had a Republican Congress.   It could have been engraved on stone tablets with Intro by a flaming bush and the Republicans would not have approved.  

Trump has zero knowledge nor interest in, a topic that requires some scientific knowledge and real evidence.   That's fine, lots of us have blind spots.  The sad part is thinking his opinion is of equal value to scientific evidence. ( or evidence of any kind).

I'm sorry you continue to leverage your dislike of Obama/ Clinton to defend Trump.    Trump has few of your personal qualities or integrity.   I hope we both have at least one improved candidate in three years.
