    GIS using social media location information and voter preferences

    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!

    Okay, how about this line of inquiry - Do you think GIS is used by the consultants that assist the legislators involved with redistricting every ten years? It seems to me that they would. But which firms, what kind of consultant does that? What kind of consultant acquires that kind of data?

    When it comes to gerrymandering, how much data is needed?

    Would love to see the courts reverse-engineer the gerrymandering process. I have a hunch that it uses GIS and a bunch of statistical methods.

    Florida Court Finds Politics Determined District Lines

    http://www.nytimes.com/2015/07/10/us...ict-lines.html

    "The justices said the legislators had violated anti-gerrymandering measures approved by Florida voters in 2010. The court also chastised the legislators for conducting much of their redistricting business in private, and for destroying pertinent documents and emails even after vowing to be transparent about the process."

    Hello, I have applied this method on my city, but not for elections. I'm looking in tweets contents of various kinds and then I try to figure out whether to categorize the various trends can be valid for: policy, market, urban civilization ... I would like you to see a video of the GIS software where I show an example to represent categories of tweet. I use QGis, along with PostGIS as a database. The plug-in is called TimeManager.

    I am specifically interested in how elections and redistricting officials use GIS.

    This article;
    http://www.freep.com/story/opinion/e...ress/31322335/

    The maps shown for 2008 and 2012 are compared on an apples to apples basis. But that doesn't ring true to me for some reason. Yes, both were presidential election years, but voter turnout has to be a factor, as does people's migration patterns.
