At risk of feeding Andy's addiction, I just discovered that Google Maps and Google Earth now do election results.
New Hampshire: Map, Dems in Earth, GOP in Earth
Iowa and Wyoming seem to have predated this particular hack.
Of course, I'm sure that the map's default of showing Democratic results will feed the conspiracy theories that the liberal technology sector is working against the right.
Update (1/10/2008): I stand corrected — they do have, at least, Iowa results in Maps. And I'm a bit behind the curve; at least the Earth version was introduced for the 2006 midterm elections. They don't appear to have a central clearinghouse for each of these links, unfortunately.
