Why not?
I posted before about a Mussolini-era Italian town name change that stuck. And consider:
It might be that those streets were mostly Nazi-era new construction rather than renaming — I’m unsure there. But given the patriotic association, in the U.S., of the name Gulf of America, I expect the next Democratic president (if there is one) will hesitate to go back to Gulf of Mexico.
P.S. Not this thread, but I think Mt. McKinley is less likely to stick.
I highly doubt the rest of the world is going to start calling the Gulf of Mexico by a different name just to please Trump. Once he’s gone we’ll all go back to calling it the same thing everyone else does and this will join “freedom fries” and “homicide bomber” and “partial birth abortion” in the list of failed Republican attempts to change the English language for political purposes.
I doubt Trump cares what the rest of the world calls it. Maybe he would care if another world leader used the internationally accepted name in a conversation with him, but most of them will be too diplomatic to do that. And I see no barrier to the name, long term, differing on maps published in other English language nations.
By the way, the Alaska State House of Representatives voted 28-10 to keep Denali. That’s the one that won’t last (assuming MAGA is defeated in 2028).
As for the Gulf of Mexico, I predict that not one of the neighboring U.S. states is going to pass a bill like that in Alaska. If I’m wrong, I’ll change my mind on long-term prospects.
If the bet is 30 days I’m going with the under.
Any truth to the rumor that the City of New York is going to change the name of the Avenue of the Americas (the street the Trump Organization is located on) to the Avenue of Guadalajara?
I mean, they already renamed the part north of Central Park after Malcolm X…
I never stopped to think how this relatively simple change of a name would affect tourism in the area. I hope the museum can survive the Trump renaming nonsense.
JB Pritzker has declared that Lake Michigan is now known as Lake Illinois and instructed Google Maps to make the appropriate adjustments. 
Hopefully, the Gov of Ky will opt to rename the Ohio River (which is owned by Ky) to the Greater Ky River.
I can see Michigan supporting that.
I believe the Mississippi river should be renamed the Ohio river based on volume and flow rates at the confluence.
And why the heck is the Gulf of California not the real Gulf of Mexico. No part of California borders the Gulf.
Gov. Pritzker’s message did mention he’ll be making a major announcement about the Mississippi in about two weeks.
Wee, I call dibs on renaming the Great Salt Lake.
I…choose…Saline drip
As a resident of the small but proud country of Luxembourg, I will start advocating that le
Jardin du Luxembourg, the well-known green space in the heart of Paris, be renamed.
I will concede— there is some national satisfaction in the knowledge that, for this prominent and much-visited site, the famously self-absorbed Parisians are stuck with a moniker that reflects the aristocratic family dynasty that originates in my adopted country and gave it its name, rather than something more properly French.
However, on the entirely selfish side, I’m tired of telling Stateside acquaintances where I live, and having them conclude, after a cursory google, that I somehow reside in a Parisian public park.
Therefore, henceforth, le Jardin du Luxembourg shall be known as le jardin à Paris avec le lac et les petits bateaux jouets. It is so ordered.
I’d like Doug Ford to unilaterally name Lake Superior to “Upper Lake Ontario,” Lake Huron to “Lake Goderich,” Lake Erie to “Lake St. Thomas,” and Lake Ontario to “Lake Fuck You Trump.” All names to be recorded on Canadian maps.
And all names to be rescinded once the Orange Shitgibbon dies, loses office, or is committed to a mental institution.
I’m sure you’re kidding…but in case someone reads this and doesn’t know: The US state of [Alta] California is just half of the region with that name. The other half, Baja California, indeed borders that Gulf (which also goes by the name Sea of Cortez, especially on old maps, but most Mexicans think of Cortez as a blend of Hitler and Andrew Jackson, so that name has fallen out of favor.)
Fair, then we’ll go with Gulf of Baja or Baja Gulf or Baja Fiord.
Would we be allowed to pine for it?
I left feedback for Google’s change. This is what I did.
An absolutely useless, but nevertheless actuall, protest.
I tried, but it doesn’t work here. I found The Mexican Gulf and on the map it said The Mexican Gulf with American Gulf in parentheses after that.
