Presidential hopeful Gareth Sheridan has said he has support in Tipperary and Laois county councils.
The businessman, who officially launched his campaign in Dublin this morning, said he is confident he can be proposed and seconded by six local authorities, but would not be drawn on the other four.
Anyone hoping to get their name on the ballot requires the support of four councils or 20 members of the Oireachtas.
A sitting president can also nominate themselves.
Mr Sheridan said his campaign is focused on housing, and that he wants to "make Ireland home again".

He pointed to article 45.2.1 of the Constitution which requires the State to direct its policy towards securing that citizens may "through their occupations, find the means of making reasonable provision for their domestic needs".
Mr Sheridan said this means working people should be able to afford to buy a home in Ireland.
He added that he would hold the Dáil to account over housing failures.
