I agree--Kag nailed it. And so has MikeAA. Trump has no centre except himself since he's probably a narcissist. He does what he needs to do in the moment. Trump doesn't fundamentally care for issues like abortion or marriage equality because they don't impinge on Trumpland and are merely cards to play in order to gain some type of advantage. I'll bet good money that Trump has never thought of the fate of a single unborn child other than his own kids before they were born. (Safe to say any surprises have been terminated.) As for marriage equality, the guy has no pulse for this stuff and with Big Business often backing LGBT interests, this is a lost cause. I am surprised more people could not figure this out.
