Brandwatch provides a political share-of-media infographic that you'll love playing with. You can compare the amount of Twitter and print discussion on 30 policy topics between media and candidates by state and time period. Pretty colors!
Brandwatch claims this technique reveals "the true thoughts of voters," better than surveys. But what can you really conclude by knowing, for instance, that Romney had more NH press and tweets than Obama about Israel and Palestine? There's a lot of information here, but to make sense of it requires a bit of extra thought. --Bill Paarlberg, editor
