Mayo

Co. Mayo

Mayo is a 5-seat constituency that delivered Aontú's first-ever Dáil seat: Paul Lawless was elected on transfers despite trailing Fine Gael's Mark Duffy, Fianna Fáil's Lisa Chambers and independent Patsy O'Brien on first preferences, alongside Sinn Féin's Rose Conway-Walsh (who topped the poll), Fine Gael's Alan Dillon and Keira Keogh, and Fianna Fáil's Dara Calleary.

Why this leans Sinn Féin

The 0.9-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.

2024 General Election — First Preferences

First-preference vote share by candidate. Rose Conway-Walsh (Sinn Féin) topped the poll with 14.3%. Bold candidates were elected — final seats are decided by PR-STV transfers, not first preferences alone.

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. .
