Polls may make for great stories, but voters should be wary of the hype. It's important to be a sophisticated consumer of polls and ask "what does that number mean," said Marc Hetherington, a political science professor at Vanderbilt University

"If you were able to poll voters on what they think about polls they'd think they're crazy," Hetherington, said. "The idea that 1,000-1500 people can make a prediction on what people think in the country is crazy."
