Once upon a time, very broadly speaking, Fianna Fail represented the small farmer and the worker and the greener nationalists. Fine Gael represented the ranchers and the pale green nationalists. Labour represented the worker and the farm labourer. The blurring occurred over decades, the charge for the centre ground speeded up throughout the 1990s. There now isn't a political handspan of difference between any of them, no more reason to put one in than another.
Political seats are jobs.
