title: Looking up GPS coordinates for United States counties
body: <p>I'm currently working on a small project to try to visualize 2012 election results based on population density, per county. I'm parsing relevant data in Python, then a colleague of mine is using AS3 to visualize the data.</p>
  
  <p>What was once just a scale-able bar graph, is soon to become a visualization on the map of the United States. It would be very useful to find GPS coordinate data per county. I've found TIGER data and shapefiles, but I assume there has got to be some collection of data that simplifies position to GPS coordinates.</p>
  
  <p>Does anyone know where I can find this data? Either downloadable or accessed via a free-to-use API?</p>
