Candidates that made list for possible Aras run
Olivia O'Leary, the well known journalist and broadcaster, has been mentioned on numerous occasions as a presidential candidate.
She was widely praised for delivering a keynote speech at the gala event at the Dublin Convention Centre during Queen Elizabeth's recent visit to Ireland.
However, she ruled herself out to Independent TDs in recent days after giving it some consideration.
Gay Byrne's name is already in the ring, with Fianna Fail leader Micheal Martin pledging support for him. However, getting the support of some Independents would boost his efforts to present himself as a non-party candidate.
He is expected to announce his final decision on the presidency next week.
John Lonergan was governor of Mountjoy Prison for 24 years and spent 48 years working in the prison service.
He would be seen as a left-of-centre candidate and is strong on issues such as social justice, drugs and community.
Last night he said nobody had contacted him about the presidency yet. "God, things couldn't be that bad," he said. When asked if he would be interested in running for the Aras, he replied: "Not at all."
