Vice President Joe Biden is in Midland, Michigan today. He's there for the groundbreaking of a new plant that will make advanced batteries for electric and hybrid cars. Michigan's governor, Jennifer Granholm, says she wants Michigan to be the battery capital of the nation and guide a revival of the state's economy and the automotive industry. It's a nice idea, Michigan getting back on its feet finding a growth industry, but what needs to happen for it to work?
