Cool initiative for those of us trying to make polling place information easily available to our constituents online -
The Voting Information Project has developed an open data format with which state election divisions can publish their voting information. Other organizations or individuals, such as newspapers, search engines, and civic-minded technologists, will parse the data contributed by the states and disseminate the information in the form of easy-to-use websites, maps, and other tools.
They have a sample tool up and running for Virginia's 2009 election, which maps your polling place location on GoogleMaps after you enter your address. Word on the street is that they hope to have similar tools for at least 25 states in 2010.
