If you want to throw you hat into the arena fine but otherwise keep your own council.
People do not look to you for wisdom or advice. They look for you to, for some brief moment in time, make their lives feel a little less bleak. Some guy who is listening to Swift with his very ill daughter because she enjoys it is not going to change his vote because of your endorsement. But once she has died he is also not going to be able to hear your song and take comfort in a happy memory. All he can hear is you ranting about something you know nothing about and that has nothing to do with your art.
So stop it.
Entertainers are a necessary part of the world. They provide something we need on a very primal level. And they should stick to that job.
Back during the Golden Era of Hollywood, when the big studios kept a stable of actors under contract, the actors and actresses were not allowed to make any public statements on any subject without prior approval of the studio PR people. And definitely no political endorsements.
Boss moguls like Sam Goldwyn knew that the American people would automatically be turned off by half if an actor endorsed a candidate. And that half would not show up at the theater to see the actor’s movies.........
