 A part of the presidential campaign is now complete. Donald Trump has announced that Ohio Senator J.D. Vance will be his running mate in the race for the White House. Vance is expected to appeal to working class voters in critical battleground states like Wisconsin, Pennsylvania, Ohio, and Michigan. Vance, who will be 40 next month, first gained fame as author of the book Hillbilly Elegy, which later became a movie.
