 As I've thought about what Senator Vance brings as a ticket for Trump, there are a number of things that come to mind. Vance is attuned to the issues of working class middle America that we've been hearing about in the conversation about his book, Hillbillyology. He'll help in states like Pennsylvania, Wisconsin, Michigan, and of course, just lock up Ohio. I'm tempted to add New Hampshire to that as well. He's going to help with the votes of military veterans, as I've written about in my column for the Washington Post.
