The Graph below takes the same data (how the votes fell in areas with different percentages of Middle-class Households ), but organises the votes into Blocs…
LEFT – Sinn Fein and AAA-PBP…
CENTRE – Fianna Fail, Labour and the Greens
RIGHT – Fine Gael and Renua.
(Interesting Note – in predominantly working-class areas Sinn Fein outpolled AAA-PBP 38% to 32% in the 2014 bye-election. This time the roles were reversed with AAA-PBP leading Sinn Fein by 7%).
