> Surely you don't think it would be legal for Congress to pass a law preventing newspaper publishers from, for example, endorsing presidential candidates? Nah, but I also reckon there's a reason the press is mentioned specifically in that amendment.
What about a law prohibiting unions from doing so?
I mean, they do in fact already dictate a lot about how both unions and corporations can operate, so yeah, prohibiting endorsement of candidates using union resources doesn't seem entirely crazy to me. Though, again, I'd rather they didn't.
