Sinn Féin TD Eoin Ó Broin has said the party is ready to go into government with anyone who will talk about serious issues.
The Dublin Mid-West candidate was speaking after an exit poll showed a three-way tie between Fine Gael, Sinn Féin and Fianna Fáil.
All parties have been put on 22% support, according to the poll of more than 5,300 people.
Mr Ó Broin told Newstalk Breakfast the party will talk to everyone.
"We made very clear from the key press conferences to the media interviews to our conversations with voters on the doors, we wanted people to transfer to pro-change candidates.
"We're hoping for the maximum number of progressive, pro-change candidates get elected today."
On the forming of a government, he said: "What we've said throughout the campaign is we want to be in government, and we want to be in government to deliver real change on the all of the key issues we campaigned on.
"Obviously we have to get through today, and get our seats and candidates elected.
"But once we start contacting the parties we'd be looking to discuss with all of them around restoring the pension age to 65, building 100,000 public houses, proper investing in universal healthcare... and obviously progressing towards a referendum on Irish unity.
"Anybody who wants to talk about that kind of progressive, positive change we're in the business of wanting to talk about them and form a government".
Asked if the party could benefit more from staying in opposition and have another election in the near future, he said: "The people who voted for Sinn Féin yesterday desperately need change, they can't wait for another year, two years or three years.
"We're ready to roll our sleeves up and do the hard graft, but others need to respond in the same way.
"If we can deliver on all of those key issues, we're reading to be in government tomorrow".
