Fianna Fáil candidates are dominating the early election tallies in constituencies across the country.
The party looks set to top the poll in almost all of the 12 Dublin constituencies, as well as most of the other constituencies outside the capital.
The Taoiseach, Bertie Ahern, Minister for Education Mary Hanafin and Social Affairs Minister Seamus Brennan all look set to be re-elected with ease.
In Dublin South Central, Fine Gael's Catherine Byrne looks set to win the seat vacated by Gay Mitchell, while the party's candidate in Dublin West, Leo Varadkar, is also polling well.
Brian Hayes may also win back his seat in Dublin South West, possibly at the expense of Sinn Féin's Sean Crowe.
Elsewhere, the early tallies suggest that Liz O'Donnell of the PDs has suffered a halving in her vote in Dublin South
Outside Dublin, several ministers also look set to top the poll in their constituencies, including Defence Minister Willie O'Dea in Limerick, Communications Minister Noel Dempsey in Meath West and Transport Minister Martin Cullen in Waterford.
Fianna Fáil's Aine Brady appears set to regain Charlie McCreevy's former seat in Kildare North, while Seamus Kirk is polling well in Louth, where Fine Gael's Mairead McGuinness is hoping to gain a second seat for the party.
Michael Smith also looks secure in North Tipperary, where Michael Lowry is likely to top the poll.
Meanwhile, Fianna Fáil should take a second seat in Kerry South, with Labour's Breda Moynihan Cronin appearing to be in trouble.
In Cork South Central, Enterprise Minister Micheal Martin is leading the running, but Deirdre Clune could take a second seat for Fine Gael.
