I believe Trump’s responsive question about equating pro-life with privacy was very well made even to the implication people can have their own beliefs as to SC decisions. The members of the Court are not infallible as to matters of social conscience. Though not yet a diehard Trumpster I give him good ratings as to expression on this issue.
I believe he didn't know the court's reasoning in Roe Vs. Wade, and that his response was a puzzled and totally honest answer. And, of course it makes no senses to talk about an abortion right being related to a right to privacy. Trump's instinctive reaction was a good one.
