JD Vance wins Ohio GOP Senate primary COLUMBUS: .
"Hillbilly Elegy" author JD Vance won Ohio's contentious and hyper-competitive GOP Senate primary on Tuesday, buoyed by Donald Trump's endorsement in a race that was an early test of the former president's hold on his party as the midterm season kicks into high gear. A onetime staunch critic of Trump whose 2016 memoir about his Appalachian childhood lifted him to fame, Vance spent much of the campaign behind in the polls. But a late-stage endorsement from Trump pushed him to frontrunner status and the two men downplayed Vance's past.
