Not a signal then? I'm not invested in Irish politics or particularly like this guy but surely, if he won it is a signal that the good people of Ireland have had enough?

The bar for getting on the ballot is ridiculously high in Ireland.

The endorsemet of 20 sitting members of the Dáil (parliament)

Or the endorsement of 4 local councils

It's incredibley unlikely that he will get on the ballot.

The role of the Irish President is basically to shake hands and as a sort of ambassador. It's almost entirely ceremonial. They sign things into law but cannot actually vetoe legislation put forward by the governent.

The President's powers include:

Appointment of the Taoiseach, members of the Government, judges and other officials;

Summoning and dissolving the Dáil (parliament), and convening the Oireachtas (wider government)

Signing legislation into law and/or referring Bills to the Supreme Court; (again, no vetoe powers)

Representing the people of Ireland;

Acting as Supreme Commander of the Defence Forces.
