First up is Google’s US Voter Info site, which is just a version of Google Maps with integrated voter information. Users can enter their addresses in order to find their designated polling place, and even get directions right from the map. If it can’t find a polling location for your address (which, curiously, it could not for mine smack dab in the middle of Chicago), it will suggest getting an absentee ballot for your state with a link directly to where you can find obtain one. It’s really quite handy if you’re not in the mood to go digging around website after website in order to find out where to go on November 4.
Even more useful is a US Voter Info Gadget that can be embedded into any third-party website or blog. The module is just a shrunken-down version of the above map, and again allows you to enter your address in order to find the closest voting location.
The latter didn’t work for him but it found my rural Georgia voting place. Here’s the Official Google Blog post about the services.
