Trump has literally zero interest in the abortion issue. The first time he was asked to give an opinion about abortion policy, he got caught with his pants down. It's safe to say that Donald Trump does not think about abortion unless forced to. He has no history with the pro-life movement. He has no interest in women's issues or human rights issues. He wants to spend his time jetting around yakking with world leaders. He has never listed being "pro-life" as part of his official platform. 

By the way, anyone that thinks protecting human life in this particular context simply means legislating against abortion has no clue either.
