The Dublin Central byelection is heating up as Sinn Féin's candidate, Janice Boylan, leads with 21% in the latest polls, just ahead of the Social Democrats' Daniel Ennis, who has 18%. Boylan's strong showing is crucial for Sinn Féin leader Mary Lou McDonald, as failing to secure this seat could raise questions about her leadership. Veteran criminal Gerry Hutch trails with 14%, but his path to victory appears challenging without a significant increase in first preference votes. Ennis is well-positioned to benefit from transfers, leading with 15% for second preferences, indicating potential strength as candidates from the left and center are eliminated. However, several factors could influence the final outcome, including a 4% margin of error in polling, historically lower turnout in byelections, and last-minute voter decisions. Currently, the Social Democrats seem to hold the advantage.
