The court has said that campaign-speech regulations can be justified to combat corruption or the appearance thereof. Trump says he has made innumerable contributions to members of both parties because, “When you give, they do whatever the hell you want them to do.”
Before he decided to solicit contributors, he said his wealth made him the only candidate impervious to corruption. It is unlikely that he would nominate to the court persons who believe that the First Amendment, properly construed, requires the deregulation of political speech. The mast-clingers should remember that Trump’s hostility to First Amendment values is apparent in his desire to “loosen” libel laws, thereby making it easier to sue or intimidate people who criticize people like him.
