Irish voters have rejected the Lisbon Treaty.
With results in from all 43 constituencies, the Lisbon Treaty has been defeated by a margin of 53.4% to 46.6%.
A total of 752,451 people voted in favour of the treaty and 862,415 voted against.
Just 10 constituencies - Clare, Dublin South, Dublin South East, Dublin North, Dublin North Central, Dún Laoghaire, Kildare North, Laois Offaly, Carlow Kilkenny and Meath East - voted in favour of the Treaty. - RTE News
From what I understand, the Lisbon Treaty has to do with the European Union. If it gets passed than the Union has more control (secularization) over a country, but if it is rejected the country is free to stick with its traditional politics.
