The current election is suspenseful without being especially interesting. Past ones were often more dramatic.
A Group at Sheffield University (The Social and Spatial Inequalities Group) have produced an animated map that should interest anyone with a taste for political history. It shows very clearly the voting patterns in all constituencies in elections between 1832 and 2005, Blue battles yellow throughout the nineteenth century, and the swathe of red that bursts on to the map in 1918 says more about the social effects of the Great War than many a scholarly article.
