Sinn Féin suffered a bruising setback on Friday when it lost the Dublin Central by-election to the Social Democrats, with political newcomer Daniel Ennis winning the seat and party candidate Janice Boylan finishing second. The result came in Mary Lou McDonald’s own parliamentary power base and raised fresh questions about Sinn Féin’s ability to turn national support into local victories.
Ennis, a former League of Ireland soccer player, said after his win: “We believe in the politics of decency, hope and inclusion.” He also said: “People want change, but they want positive change.” Dublin Central had been held by former Finance Minister Paschal Donohoe until he quit last year to join the World Bank.
The loss mattered beyond one constituency. Sinn Féin has been trying to hold its place as the main opposition force after its national poll lead plummeted in the run-up to the 2024 general election, and the Dublin defeat came just as the party was also facing trouble in another race in Galway West. That contest was still being counted on Saturday, but Sinn Féin’s candidate there was facing certain elimination.
Ireland’s ranking-based voting system often produces long counts, and by-elections rarely break for parties tied to government. Fine Gael and Fianna Fáil were not running in Dublin Central, yet the seat still slipped away from Sinn Féin. The Social Democrats’ win also lifted them to second place among opposition parties and ahead of Labour in parliamentary numbers.
McDonald, who has led Sinn Féin since 2018, tried to draw a line between one bad result and any wider judgment on her leadership. In Galway, she said: “There is no question on the leadership. I am the leader of Sinn Féin.” She added: “I lead it on days when we’re on a winning streak. I lead us on the days when we’re not lifting the cup.”
The tension inside the result was sharpened by the final numbers in Dublin Central. Gerry Hutch finished in fourth place after campaigning on a hardline message that called for Somali immigrants to be interned without trial in a former army base. His showing underscored how fractured the field was, but it did little to soften the blow for Sinn Féin after a contest it was expected to contest from a position of strength.
Eoin O’Malley summed up the scale of the problem bluntly: “It’s a bad day for Sinn Féin because, as the main opposition party, it should be leading and winning these seats.” The party now faces a sharper test than a single by-election defeat. It must show that its setbacks in Dublin and Galway are temporary, not a sign that the ground beneath its support is still shifting.
