Trump's response to the question was the sort of (prepared?) response that we should expect him to give on national TV during a debate. His earlier endorsement, in a different setting, of a radical-liberal pro-abortion jurist reveals the real Donald Trump, in my opinion.
Why don't you even consider the possibility that Trump is a fraud? After all, he is obviously a world-class narcissist and world-class blowhard. What makes you think Trump is sincere about anything of real importance?
P.S. Marilyn vos Savant is badly overrated.
