If you are looking for a classroom idea, consider having your students participate in the Ed Community’s Presidential Mapper at:  http://edcommunity.esri.com/projects

This quick little activity will record your student’s vote, geocode their location (based only on city/state) and create a map and charts of all votes.  You can also download all of the data (even the data your students just entered) into ArcGIS Explorer for further viewing and analysis.
