 Mr. Trump chose Senator J.D. Vance of Ohio as his running mate this week, picking a one-time critic who became a loyal ally and now is the first millennial to join a major party ticket. Western Carolina University professor Dr. Chris Cooper told WLOS, I don't think J.D. Vance is going to hurt the Donald Trump ticket. I don't think it's going to help the Donald Trump ticket. I think he will be, you know, sort of the second tier of that ticket as Donald Trump would want.
