 KFXZ 1520. I'm Jeff Palermo. Republican presidential nominee Donald Trump is named Ohio Senator J.D. Vance as his running mate. Vance gained fame in 2016 with the publication of his memoir, Hillbilly Elegy. The former Marine and Yale graduate was elected to the Senate in 2022. He's only 39 years old, but Republican State Treasurer John Fleming believes his youth will be the foundation for the future of the Republican Party. Trump's numbers have been growing dramatically among young people.
