More evidence that the mainstream media distorts the truth

As if you didn't already know that most of the garbage fed to you by your 24-hour news networks is distorted if not outright false, here's more evidence that they distort the polls.
It's Facebook's "Election Pulse," tracking how many supporters there are on Facebook. It's a good test to see who would support whatever politician, those concerned and politically involved enough to post their opinion to Facebook. Granted, this is primarily the demographics of college students, but I wonder if preferences can change that much among demographics.
