Daniel Ennis of the Social Democrats leads trader consensus in the Dublin Central by-election at 70 percent implied probability, driven by expectations that left-leaning transfers will favor him under Ireland’s single transferable vote system once lower-polling candidates are eliminated. A recent Ipsos B&A poll conducted in mid-May showed Sinn Féin’s Janice Boylan ahead on first preferences at 21 percent to Ennis’s 18 percent, with independent Gerry Hutch at 14 percent and Fine Gael’s Ray McAdam at 13 percent. The race remains tight heading into the May 22 vote to replace the vacant seat, with analysts highlighting Ennis’s local profile and potential to consolidate support from parties including Labour and the Greens. Hutch’s independent candidacy has generated media attention but faces constraints from his criminal associations, while Fine Gael and Fianna Fáil candidates trail amid broader government unpopularity on housing and cost-of-living issues.
