The protocol rule is that a title that refers to many people, like "senator" or "judge" (or "professor") may still be used after a person is no longer in the office, but not "president." George Washington established this, retaking the title "General" after he left the presidency.
"Senator," yes. The controversial cases are "governor," because "Governor of Texas" is a position like president, but there are 50 governors; and "secretary," because "Secretary of State" vs 13 (or whatever) various Cabinet secretaries. GW Bush and Clinton might both be misters.
Secretary is also considered a higher position than Senator, but I was referring to the post I was replying to questioning retaining the “Secretary” title.
But then the same logic applies. There are lots of other presidents in the world. How are presidents from other countries referred to when talked to in the US?
I think generally order of precedence (and assignment of titles) is within a country; I’m not sure how it works when you have, say, a mix of ministers between countries.
Only students at university refer to the professors as Professor. Outside the university - even at professional conferences - their title becomes "Doctor."
Proposal that Donald J Trump really ought to register a legal name change to "Donald Trump President" so he can legitimately be addressed as "Mister President" like he clearly wants.
🤔 Huh.
(Surprised because in his book Bully for Brontosaurus, Stephen Jay Gould describes talking to Jimmy Carter. Carter was long out of office, but was still introduced as President. Gould said this was customary.)
