The real reason Hillary Clinton has a short VP list

Sherrod Brown looks in some ways like a very tempting vice presidential pick for Hillary Clinton.

He doesn't have an enormous national profile, but inside the Beltway he's known as a stalwart of the liberal wing of the party's congressional caucus. Unlike Bernie Sanders, he's a loyal party man. But he has a similar disheveled populist anti-fashion to go along with an extensive track record of support for labor unions and skepticism of the forces of globalization.
