Even an overwhelming vote margin can be interesting to map, but I’m a bit disappointed with the maps of the Irish referendum held last Friday on whether to repeal Ireland’s constitutional ban on abortion. The official Referendum Ireland website, the Irish Times and RTÉ News all use two-colour constituency map (one colour for yes, another for no); the Irish Times goes a little further and shows choropleth maps for the yes and no sides, but quartiles don’t reveal very much either. The Guardian and even Wikipedia show more granularity. [Maps Mania]
Update: Lots and lots of choropleth maps on the Irish Political Maps Twitter account.
