1st of all, it was a hypothetical question that will never come to pass.
Secondly, all of Donald Trumps positions show that he is an emotional man. In some ways a very sensitive man. He Romanticizes women and he doesn’t like to think about abortion because it is an ugly subject. He is not a polished politician. He doesn’t regurgitate shibboleths that he rehearses that tell people what they want to hear. The subject makes him sad and he doesn’t like to think about it, he’d rather let somebody else handle those things, and that is what a business man does. He allocates responsibility to the best person for the job on subjects he isn’t an authority on.
