Simon Harris
Tánaiste & Leader of Fine Gael
Ireland Thinks/Sunday Independent asks whether people are satisfied or dissatisfied with each leader's performance, but only publishes the satisfied % — no dissatisfied breakdown is shown here because none has been published to verify. "Weighted avg" is satisfaction averaged across 9 real readings with a 3-month recency half-life (weighted by actual elapsed time between polls, since this series isn't evenly spaced), so it's less sensitive to any single reading's noise than the latest figure alone.
A separate, one-off Business Post/Red C, via Irish Examiner favourability reading (May 2026) scored Simon Harris 36/100 — a different question and scale, not directly comparable to the satisfaction % above, shown here only because it's the one other real reading found for this leader.
Satisfaction over time
% satisfied with Simon Harris's performance. Solid dots are each real poll's actual reading; the dashed line is a 3-month recency-weighted average (weighted by real elapsed time, not by reading count) with a shaded ±— pp margin-of-error band. These are the 9 real, individually-sourced readings found since January 2025 — coverage of this specific question is uneven, so gaps of several months between points are real gaps in available reporting, not missing data on this site's part.
Simon Harris became Fine Gael leader and Taoiseach in April 2024, the youngest person to hold the office. He became Tánaiste in January 2025, initially as Minister for Foreign Affairs and Trade, before moving to Minister for Finance in a November 2025 reshuffle after Paschal Donohoe departed to take up a role at the World Bank. Under the coalition's rotating-Taoiseach agreement, he is due to become Taoiseach again on 16 November 2027, when Micheál Martin steps down.
