This weekend on Lake Effect : During an election season, polls are always big news. We tackle some fundamental questions about polls and how the news media covers them.

Plus we have the latest edition in our storytelling series Ex Fabula. Guests: Charles Franklin, Marquette Law School poll director; Craig Gilbert, Milwaukee Journal Sentinel Washington bureau
