Counting will start this morning to decide the winner of the by-election in Dublin Bay South.
Polling stations closed late last night in the race to replace former Housing Minister Eoghan Murphy. Sinn Féin's Lynn Boylan will be hoping for a repeat of what the party pulled off in Dublin Mid West two years ago when a low turnout bucked the trend to cause an upset.
Internal party polling shows those three candidates are likely to be well ahead of the rest of the field.
However for many It's being seen as a two-horse race between Fine Gael's James Geoghegan and Labour's Ivana Bacik.
