On Sunday I went to Portlaoise with a group of enthusiastic young people to campaign at the All-Ireland under-21 football final between Dublin and Galway. All politicians know we get the rough with the smooth out on the street and we got both that day. A man came up to me and told me he was voting "No" because he works in Aer Rianta. I had heard many arguments but this was a new one. I asked him to explain the logic in that argument. He told me that he was given a sheet in work stating that an article in the Nice treaty provided for the privatisation of Aer Rianta.
