That is an unfortunate aspect; but not a deal-killer; the problem is the secularized culture in which voters have allowed abortion to remain legal so they may practice their Marxist sex. We need a religious revival, but a president cannot bring that about. The the topic at hand was the claim that Trump had no idea whatsoever of Constitutional law. Just because he sounds like a Brooklyn pipefitter doesn't mean he is unable or unwilling to understand the fundamentals of our system. To make an analogy, he has had to master reading blueprints although he isn't an architect or engineer. He knows what a foundation is, and that the Constitution is our national blueprint. (Just an analogy; not an invitation to split hairs over the difference between a blueprint and a legal document...)
But we can hold the line by not electing someone who will put an open pro-abort on the Court.
And also, I’m sure he has the best consultants on this matter (anchor babies). He always has the best people advising him and working for him. That’s part of the secret of his success.
