I went to Netroots Nation in San Jose this year. The most interesting panel I attended was on “tracking” where someone from one political campaign follows around a candidate at their various public events and records what they do and say. The various members of the panel spoke about how powerful some of these videos can be citing examples from early hits with George Allen’s “Macaca” to Romney’s ” the 47%” I knew this happened but I was unaware of just how sophisticated the process had become at the national level.
