Trump running mate J.D. Vance vows to fight for 'forgotten' workers

Donald Trump's vice-presidential running mate, U.S. Senator J.D. Vance, presented himself to the nation on Wednesday night as the son of a forgotten industrial Ohio town who will fight for the working class if elected in November.

In chronicling his hardscrabble journey from a difficult childhood to the U.S. Marines, Yale Law School, venture capitalism and finally the U.S. Senate, Vance, 39, introduced himself to Americans while using his story to argue that he understands their everyday struggles.

"I grew up in Middletown, Ohio, a small town where people spoke their minds, built with their hands and loved their God, their family, their community and their country with their whole hearts," Vance said, formally accepting the party's nomination at the Republican National Convention in Milwaukee.

"But it was also a place that had been cast aside and forgotten by America's ruling class in Washington."

He accused "career politicians" like U.S. President Joe Biden — who Vance noted has been in politics longer that he has been alive — of destroying communities like his with ill-fated trade policies and foreign wars.

"President Trump's vision is so simple and yet so powerful," he said. "We're done, ladies and gentlemen, catering to Wall Street. We'll commit to the working man."

In a sign of his potential value to the ticket, he also repeatedly appealed to the working and middle classes in Michigan, Pennsylvania and Wisconsin specifically — three Rust Belt swing states likely to decide the Nov. 5 election.

Vance described his grandmother, "Mamaw," who raised him as his mother struggled with addiction — and acknowledged his mother, Beverly, who was on hand to watch him speak.

"I am proud to say that tonight my mom is here, 10 years clean and sober," Vance said. "I love you, Mom."

A visibly moved Beverly Vance mouthed, "I love you, J.D.," while delegates gave her a standing ovation.

Vance described his grandmother as someone who both "loved the Lord," but also "loved the F-word."

"She was an old woman who could barely walk, but she was tough as nails," Vance said.

Vance's prime-time debut, less than two years after he first assumed public office, capped a rise that coincided with his transformation from a fierce Trump detractor to one of his most devoted defenders.

He is one of several high-profile Republicans, such as U.S. senators Ted Cruz and Marco Rubio, whose reversal from critic to loyalist has underscored Trump's takeover of the party.
