I have added some new data to the Redistricting section. Are you interested in finding out which congressional districts overlap with which state senate districts or state rep districts, or even which counties are involved? I've run all the districts through the computer and created this simple utility to give you more information about the districts. Check it out!


Welcome to Illinois Election Data, a data driven website I've created to share and display useful campaign data on Illinois elections. During my time working on campaigns I have amassed a very large number of files on Illinois election data. Having been through this exercise so many times I know how difficult and time consuming it can be to have to build the same data files over and over and I have a lot of sympathy for those who have to do so. I created this site to try to provide a lot of the basic data in an easy to see, understand and use format to help the overworked campaign staffers who work too many hours.

There is quite a bit of information in this site:

  • MAPS - Click on MAPS to select various types of vote total maps with the results color coded on top of Google Maps.

  • VOTE ANALYSIS - Click on VOTE ANALYSIS to see spreadsheet style data on election results, vote share and/or turnout organized by county, ward, township, media market and/or region.

  • BUDGETS - Click on BUDGETS to see monthly line item fundraising and spending for previous campaigns as well as payroll and media buys.

  • REDISTRICTING - Click on REDISTRICTING to overlay various maps to see how they are different. You can look at the new ward, congressional, state house, or state senate boundaries and see how they compare to the old boundaries, or with each other or even with county boundaries.

If you have any questions check the FAQ for more info.

Over time I plan to add more data and occasionally use this blog to highlight or add some depth to some data I find particularly interesting. If you want to keep an eye out for updates to this site feel free to follow its Twitter feed (see right hand sidebar), new posts will automatically be tweeted as well. Enjoy.
