Town Square: What do Poll Numbers Mean?

"In the latest poll..." How many times have you heard that phrase? This week a handful of polls charting the President's approval rating is being bounced around online, in print and over the air...but how much weight should we really give these snapshots in time? And what do poll numbers mean for a Presidency when we look back at them years down the line? UH professor of political science, Colin Moore is teaching the science behind polling to his students this week. Tonight we'll talk with him and Grassroot Institute Executive Director, Tim Lussier, about their take on polling and what we should take away from all the samples.
