I notice on here that you have this chart on the back, and your instructions say if you use the QR code, you can get all the answers using the interactive online version. I took out my camera and did exactly that. I then tried using the part about finding your polling station. I clicked on the pink bits, on the interactive site, and I was brought to something where I could fill in my postal code and get a polling station.
I can't determine what accuracy this has, but I'm really impressed. I wonder if you could tell us more about this effort, which, as far as I know, is not being replicated at the federal level and perhaps should be.
