La Carte des Divisions de la Droite
The French left-wing political party PS have produced this Google Maps mashup to highlight the mistakes that they believe the French right-wing party UMP have made in the current local elections campaign.
The map includes mainly reports from newspaper articles. However the map also includes a form for supporters to send in their own relevant stories. It is possible to embed the map in a website or blog by cutting and pasting a short piece of code.
