Salam on Biden's role as attack dog: all about 'working class white guys'

Vice President Joe Biden made a meat-and-potatoes pitch to working class voters in Ohio, a key state for President Obama's campaign. Biden described Republican Mitt Romney as a man who can't relate to real people. "They don’t get us. They don’t get who we are,” Biden said. “My mother and father dreamed as much as any rich guy dreams.”

Is Biden the president's most effective tool in places like Ohio? CNN contributor Reihan Salam says Biden's a better representative than the president in appealing to a key segment of the population: "working class white guys."
