Why else? Because he becomes the most powerful leader in the world. That would feed his ego and allow him to make more money. But, sure, he is only doing it out of the goodness of his lil ol’ Conservative heart.
I don’t doubt that Trump wants America to be great. He wants to create HIS best version of America. I don’t believe his best version is really a conservative America even if it’s a strong America. I don’t want to gain power and riches if we lose the soul that America is based on.
Name me on president, or candidate, who DOESNT do it for ego, power and riches.
