Thanks to rougemapper, we have election data for Illinois (presidential). He’s sent me data for a couple more states, so I’ll be looking at those in the next couple of days. And now, also from rougemapper, AZ, MN, NV!!
Also, DE,ME and NH have block groups.
A couple of people have had trouble with the app not launching, even though they have the correct version of Silverlight. If you run into this, try deleting the Silverlight application storage. If you load any Silverlight app, right click to get to a Silverlight dialog box. Go to the Application Storage tab and delete storage for gardow.com.
Thank you to everyone who has contributed. And thank you so much, DavidNYC!!!
