Actually, no, he isn’t my president. He’s president of the United States. There are 50 of them, and I am not one of them. That’s the whole point of the USA — he is not a king; some people seem to think that’s just a matter of a different title, or of being limited to a certain term, but it’s not. It’s a fundamental difference.
That’s why I very strongly object to those shuls who say Hanosen Teshu’a Lam’lochim, simply substituting “The President and Vice President” for “His Majesty the Kaiser”; that entire tefillah is completely inappropriate for any American shul. It’s literally un-American. If you want to say some prayer Lishlomah shel Malchus, find or write one for the United States themselves and for their constitution, not for the functionaries who are currently employed to manage them. That is precisely what makes them special.
