Fitzgerald was Taoiseach (Prime Minister) for the bulk of the early and middle part of the nineteen-eighties. If anything that period was even more crisis-ridden in Ireland than the present moment and his governments failed to address the many crises successfully. The failures were not for want of trying. He sponsored a movement toward constitutional revision, an opening to a rearranged relationship with Northern Ireland and some tentative intiatives in economic reform. Every initiative failed and in most cases had perverse results. The New Ireland Forum and first Anglo-Irish agreement, for instance, were designed to outflank Sinn Fein and bolster the SDLP. The proposals he actually came up with were so politically impossible that they drove Mrs Thatcher into a restatement of the integrity of the United Kingdom (the famous "Out, Out Out" comment in 1984) and shattered the possibility of a nationalist solution brokered by the SDLP and Fine Gael. The long-run consequence was that the eventual settlement was shaped as a reaction to his ideas and led to the rise of Sinn Fein.
The "Constitutional Crusade" had the same result. The proposal to liberalise the 1937 constitution mobilised the pro-life amendment campaign and contributed to the domination of Irish public life by the issue of abortion for a decade. In 1986 the campaign for the introduction of divorce in Ireland was so badly prepared that the provision was not only lost, but was voted against by a two-thirds majority. This despite the fact that in principle most people were in favour of the idea. As a politician he went through a recurring pattern. He seemed to fail to understand that in politics you have to win, you have to create the solution and the alliance committed to that solution in order to construct the institutions that in turn shape the life of the political community. If you don't find a solution for the political community someone else will. My suspicion is that his failures directly led to the dominance of Fianna Fail in the following period.
Even if the details of Irish political history are not close to your heart there is something important to learn from Fitzgerald and his politics and this is about the nature of politics itself. He never found a way to make his liberal, or more properly Christian Democrat, values and norms speak to the specific and local problems and situations he faced. I suspect, and this again I can only suspect, that this was because he had been captured by revisionist historiography. From that perspective the Irish Republic was fatally tainted by its origins in an act of violence in 1916 and the core political work to be done was to realign the polity to norms of legality. Much of Fitzgerald's politics can be understood through this optic of rescuing the polity from its provisional status. This disposition crippled him as a Prime Minister. It made his values and ideals more real than the polity he had responsibility for. So he lost again and again, because he was not crafting a solution for the time and place he found himself in, he was not slowly drilling the hard boards. When confronted with more robustly integrated models of ideals and a community, on the part of Unionists, Nationalists or even religious fundamentalists, he became immobilised and consistently overpowered. What he seemed incapable of doing was giving shape and form to the political community that was actually there before him; the "actually existing Irish Republic". In my view the damage he did to the credibility of the Irish liberals and even the left, effectively to respond to the aspirations of the population was fatal. By being nice, he made it hard for us to be good, and we are living with the consequences. Salus populus ultima lex.
