The President has a personal life and has personal views and opinions that he has a right to express. Yes, he is in public office and is “supposed” to represent his constituents honorably, but regardless if he does or not, shouldn’t matter. He is not a king with unlimited legislative power, he is a constrained president of a country that restricts him through the Constitution. No matter what he posts on social media has any effect on the law. He can rant and rave all day, but that doesn’t mean a thing unless it goes through Congress.
