"Rural" makes an appearance in chatter about J.D. Vance, but not in his convention speech

This is from the New York Times right now:  

Live Election Updates: J.D. Vance Addresses Republican Convention

A night focused on foreign policy featured fiery denouncements of President Biden on his policies and age. Donald Trump Jr., the former president’s son, assailed Democrats and the president.

Here’s what’s happening:

In the biggest speech of his political career, Senator J.D. Vance connected his difficult upbringing in rural Ohio to challenges now confronting the working class, decrying Democratic policies and Wall Street.

To be clear, Middletown, Ohio, population 50,000, is not rural by any measure.  Also, Vance did not himself use the word "rural" in his speech. 

Here's a report from The Hill's live reporting on Vance's speech, which played to "rural" and/or "hillbilly" themes:

Vance shared a story about his grandmother that drew loud applause from the audience.

“My Mamaw died shortly before I left for Iraq in 2005, and when we went through her things we found 19 loaded handguns,” Vance said, prompting cheers and chants of “Mamaw.”

“Now, the thing is, they were stashed all over her house … This frail old woman made sure that no matter where she was, she was within arm’s length of whatever she needed to protect her family,” Vance said as the crowd cheered.

This is a quote from the NewYork Times story about Usha Vance's introduction of her husband's acceptance speech (emphasis mine):  

She leaned into the story about her husband’s impoverished upbringing and the laws of opposites attracting, highlighting their different backgrounds.

“When J.D. met me, he approached our differences with curiosity and enthusiasm,” Ms. Vance said. “He wanted to know everything about me, where I came from, what my life had been like.”

The couple met at Yale Law School, where Ms. Vance helped Mr. Vance organize his ideas about social decline in rural white America, the basis of his breakout memoir, “Hillbilly Elegy.” They were married in 2014 in Kentucky and have three children. She is the daughter of Indian immigrants.

Here's an interesting tweet from the right, but it doesn't ring true.  

I exist in a very lefty media ecosystem, and I've not (yet) seen the left talking of Vance's "insufficiencies."  I've not seen his class of origin made an issue--nor, as of yet, any "insufficiency."  What I am seeing made an issue of is Vance's increasingly intolerant leanings.
