Does anyone know if the political candidates and their consultants use a mash-up of GIS address data, social media location information, and voter tendency data to advise their clients? It occurred to me last week that this might be happening when Facebook asked me at the top of my timeline whether I voted or not. I can only imagine the value of such a dataset to political candidates and consultants that includes all my probable home location, a general sense of my attitudes and "likes," and whether or not I am a regular voter. I can only imagine the power of that data when geocoded in a GIS. Plus, what about mashing that data with phone survey information. Couple your answers with my hypothetical Facebook dataset, and you have a very powerful predictor of election outcomes. Wow!
