Today on “Post Reports,” we’re talking about the transformation of one candidate from never-Trumper to Trump’s pick for Ohio’s open Senate seat. Read more:Back in 2016, commentator and venture capitalist J.D. Vance was known for his memoir “Hillbilly Elegy,” about the ravages of poverty and drug use in his Ohio town.
