Today's "Morning Shots" is heavy on poll data. As an old school and recovering market researcher, let me point out that with the near elimination of land lines, the ability to obtain a true random sample of Americans is impossible. Applying various weightings to correct for the biases caused by who tends to cooperate in phone-based polls is a dark and often inaccurate magic.

And we don't even answer our land line anymore unless caller ID says its someone we know. Otherwise, it's almost 100% spam.

Thank you. My Poli Sci degree is forty years old and even I remember what crap your results are if your sample is skewed.
