I've recently finished work on http://elections.barnet.gov.uk. This was a really quick micro site turned around for the elections in nine days. The brief was to "do a bit of social media and to make it easy to find polling stations and candidates". It was my first adventure in Drupal and was part of a larger piece of work to try to demonstrate the value of open source to a local Government client.
All feedback welcome. I was a bit disappointed that I could not get post code filtering happening. It would be really nice to return a list of things that are near you based on a post code search. We might invest a bit of money after the election hiring a real developer who could make that happen.
