The Dublin Central and Galway West by-elections, held following the resignations of former Minister for Finance Paschal Donohoe and President Catherine Connolly, are set to reveal crucial insights into the electorate's mood. In Dublin Central, Sinn Féin's candidate Janice Boylan will be a key indicator of the party's strength, especially after her tumultuous history with party leader Mary Lou McDonald. The performance of gangland figure Gerry ‘The Monk’ Hutch is also critical; he aims to improve upon his previous showing. The Social Democrats, led by Daniel Ennis, are looking to capitalize on a potential decline in Sinn Féin's support. Meanwhile, Fianna Fáil's John Stephens is at risk of achieving one of the party's poorest results ever, polling at just 4%. In Galway West, Labour's Helen Ogbu has been confident but faces challenges after a weak debate performance. Additionally, independent candidate Noel Thomas, known for his role in recent fuel protests, hopes to leverage public sentiment for a strong showing. The 'Vote left, transfer left' pact among left-leaning parties could also influence outcomes significantly, as could Sean Kyne's bid to break the government's by-election curse.
