WEATHER ALERT
Which Polls Can You Believe
As we head into the early voting cycle you've likely been inundated by the media with polling data. But, one poll can often conflict with another. Take North Carolina for example. One poll has Romney up by four points another has Obama up by two points. It's a similar story in other swing states as well. "House effects" are when one polling company tends to lean more republican or democrat. Much of that is determined by the demographic they're polling and the questions they ask. Mass Communication professor Dr. Mark west says the polling data is not a reflection of any party preference.
