As the Trans-Pacific Partnership looms, a look back at what NAFTA changed in America.
Exports from big states like Texas, California and Michigan have soared since the 1990s when the North American Free Trade Agreement opened U.S. markets to Mexico. But not every state has been as savvy promoting cross-border trade.
