nCube definition


The election result data we hold includes over three hundred party labels, so we have simplified them to these seven simple categories. Of course, most candidates in most elections, and almost every candidate who won, was standing for one of the main parties, but an enormous range of labels have been used by one or two candidates. These groupings have been defined based almost entirely on the party labels, rather than detailed research into party policies, but including words like 'Labour' or 'Conservative' in ...


your party label says a lot about where you stand, and even more about the people voting for you. 'Left' means broadly speaking candidates to the left of the Liberal or Labour parties, 'Right' candidates to the right of the Conservatives. 'Nationalist' means any kind of nationalist, even including Isle of Wight nationalists.
