Just like God chose Saul. Just like God chose Caesar. Just like God chose Nero, and Stalin, and even Hitler. Our God is sovereign. Even when we don’t understand His choices, He is sovereign. It’s one of the comforts that comes with Christian faith.
But remember one thing: God can choose to punish as justly as God can choose to bless. Trump could be either. He could be neither. But God is sovereign no matter what.
