Dublin South-West

Co. Dublin

Dublin South-West is a 5-seat constituency covering Tallaght, Templeogue and Firhouse. Sinn Féin's Seán Crowe topped the poll, and People Before Profit-Solidarity's Paul Murphy held the fifth seat — one of a small number of PBP-Solidarity TDs returned nationally — alongside Fine Gael's Colm Brophy, Fianna Fáil's John Lahart and Labour's Ciarán Ahern.

Why this leans Sinn Féin

The 2.1-point gap between the top two finishers here in 2024 sits on top of a longer pattern: Sinn Féin's national first-preference vote share has run 6.9% in 2007, 9.9% in 2011, 13.8% in 2016, 24.5% in 2020, then 19.0% in 2024 No digitised constituency-level results exist here for elections before 2024, so this is Sinn Féin's country-wide trend, not a claim about this seat's own history — but a party that's dominated the national picture for this long is a big part of why its 2024 local result, and this lean, look the way they do.

Under PR-STV, surplus and elimination transfers decide the final seats, so a candidate can be elected from well below the quota — or miss out despite a strong first count. .
