This November 19 New York Times editorial attempts to explain why the Times feels that some corporations should be free to spend money discussing candidates for federal office, but other corporations should not be free to do that. But the obvious question not answered in the editorial is “Who or what is press?” The New York Times seems to feel that it there is a clear line between press corporations and other corporations, but that is no such clear line.
Scholars find that when the First Amendment was written, “press” didn’t mean a certain category of businesses; it meant anyone who disseminates information via the printed page. Thanks to Rick Hasen for the link.
