For Comparsion the 1998 Treaty of Amsterdam referendum, though it must be said some of the constituencies boundaries *may* be wrong - data on this is actually difficult to find. But the contrast to Nice I and Nice II is quite noteworthy (especially given that - more so than Nice - this treaty was about giving slightly more democratic reform - reform of the EU parliament especially.)
Things of Note:
1. Turnout: Much higher than Nice I and still higher than Nice II - which were held respectively 3 and 4 years later.
2. In Dublin the pattern did not change much from Nice (West and North Central Dublin being most Anti): But South (East) Dublin here was not the most pro-EU part of the country - that would be rural connacht - and the number one constituency for yes was Longford-Roscommon (66.72%) while in both Nice referendum Dun Laoghaire recorded the best "yes".
3. What happened in South West Munster? Nice II did better here.
4. Donegal was just below the national Average here. So what happened in Nice? (I suspect it has something to do with the fisheries...)
As I said the Fisheries and the common belief in Donegal that they are constantly ignored by the other 25 Counties and by Dublin in particular. I may be wrong but..
As for Kerry North - the Anti-EU vote and the Sinn Fein vote are probably interconnected. Though I admit I know very little about this constituency except that it is probably out of all the constituencies the most dependant on Tourist Income for their local economy (that's a guess btw).
I'm not too sure tbh; all I can recall is that it was held on the same day as Nice I (and the International Criminal Court referendum) and the other two were EU prerogitatives. I suspect it has something to do with putting the ban in the constitution - but I can't be sure on this. And up until 1990 or so there were "Death Row Prisoners" IIRC in Ireland though none were ever executed or were ever had a chance of beinge executed despite the sentence. (Obviously there weren't many; and one of those prisoners IIRC was later found to be innocent.)
Btw Jas, do you recall the 1999 Local government referendum - apart from my bafflement at what exactly it was about - would you happen to have any idea why it was so strange - Turnout wise? 75% in Leitrim, 34% in South Dublin? It was held the same day as EU parliament elections if that explains anything..
