Politics[]
In 1918 Dublin St Stephen's Green gave Sinn Féin almost two-thirds of its votes. The minority was fairly evenly divided between the Irish Parliamentary Party and the Unionists.
In common with other Sinn Féiners, elected in 1918, the Deputy did not take his seat at Westminster but instead participated in the revolutionary Dáil Éireann.

^'[This] by-election ... revealed how deep the divisions in unionist ranks ran, but it was also a harbinger of the future. Senior figures within the Unionist Party were not inclined to contest the seat, especially as the new nationalist-backed ‘independent’ candidate, Laurence Waldron, was a stockbroker and former unionist who would be a moderating influence in the House of Commons. Several leading business figures, including Sir William Goulding, chairman of the Great
Southern and Western Railway, and Lord Iveagh, head of the Guinness dynasty, resigned from the Unionist Representative Association in protest at a grass-roots revolt that led to the association supporting the candidacy of Norris Godard, a Crown solicitor. It was a foolish nomination, as Godard could stand only by relinquishing his lucrative government post, which he declined to do. The former Unionist MP for the constituency, James Campbell KC, was available to stand and had the added advantage of being wealthy enough to finance his own campaign, but the Unionist Representative Association would not have him. There followed an unseemly row about the rival candidacies of another lawyer, C. L. Matheson, and Michael McCarthy, a colourful renegade nationalist from Cork who was popular with militant unionists because of his books denouncing the evils of Catholicism. Matheson secured the nomination but, as expected, was defeated by Waldron.' - Pádraig Yeates, 'A City in Wartime – Dublin 1914–1918: The Easter Rising 1916', [2]Archived 15 January 2017 at the Wayback Machine
