The proper English is “Puerto Rico’s governor”, or alternately, “the governor of Puerto Rico.” You talk like a Russian.
I suspect this is going to be a huge story. BBC World News, today, broadcast an interview with a Puerto Rican official who said that everytime she tries to find out when water or food or fuel might be coming in, she’s told that there’s no one who can tell her because they’re all in planning meetings. (I’m not seeing that story available online yet; maybe tomorrow.)
Trump’s few tweets about P.R. seem to emphasize that it’s all their own fault:
Sounds more Californian. Like, “Take the 101 to the 405 to meet the Puerto Rico Governor.” 
You got a link, fucknut? (Or do you rely on other posters to provide links to what you quote?)
Tell that to CNN. Or The Guardian: "The Puerto Rico governor, Ricardo Rosselló, is now warning of a “total collapse of the energy system in Puerto Rico”. "
Good save, comrade!
You said "The Puerto Rico’s Governor. it’s the possessive that makes you sound like a rube. Or a moron.
“The Puerto Rico governor” or “the Illinois governor” is markedly different from “the Puerto Rico’s governor”, глупый жопа.
(emphasis added)
Some Russian controlled place? On Putin’s payroll? 
Tell that to PBS: “Back in 2015, the Puerto Rico’s governor signaled it couldn’t pay back its debts, telling The New York Times that the island was nearing an economic “death spiral.””
So now you accept PBS as a legitimate source? Considering that PBS has standards and doesn’t make it a habit of such things, I’ll put down to a typo.
You, on the other hand, have no standards and I’ll put you down as an idiot.
So how long did it take to find that?
Always did. You don’t? So - that PBS article - does using the possessive make the PBS sound like rubes? Or is it morons?
n/m
Oh for crying out loud, what does it take to admit you’re wrong?
Government web site: “Val has also served in senior staff positions for the California’s governor”
Counterpunch magazine: It’s pay-to-play politics, and the California’s governor knows the game well.
A law office web site: Lawmakers have since passed the bill and it has now been placed on the desk of the Florida’s governor for his signature.
Those are some examples of pretty shit English. (And I tend to be on the descriptivist side of these debates. Is there any indication this is becoming a grammatical construction? Honest curiosity as a lover of English in all its forms.)
For your first link, here’s the actual page. No incorrect use of the possessive.
So other people use the same improper usage as you did. Why does that prove you’re right?
How about linking to a style writing guide that addresses the issue.
From my research, I can’t find anything that says this is idiomatic English. To me, the “the California’s governor” is ungrammatical in the linguistic descriptivist sense, not the prescriptivist styleguide sort of sense. It’s either “the California governor” or “California’s governor,” not “the California’s governor.” Does that seriously sound like idiomatic English to you, Okrahoma?
Yes, it does. Can you find anything that says it is wrong?
Here’s another CNN example: It’s an “unbelievable loss,” the Delaware’s governor said on CNN’s “State of the Union.”
And especially for the lefties: “Orlando’s Multicultural and Progressive Voice”: “Perhaps Florida Governor-elect Rick Scott and High Speed Rail (HSR) officials in the state could learn a thing or two from the Wisconsin’s governor-elect, Scott Walker who is opposed to a high-speed rail line between Milwaukee and Madison.”
Maybe the writing is being offshored. Trump should like that. He’s done so much of it himself.
Or do want your English skills to be compared to someone for whom English is a second language?
Trump does love himself the uneducated. So many of them voted for him.
