Professor Groseclose will discuss a way to measure quantitatively the slants of various news outlets.  He finds that nearly all mainstream news outlets have a liberal bias.  He estimates that the bias has shifted the views of voters by about 25 “PQ” points on a 100-point scale—approximately the difference between the average American voter and the average Texas voter.
