From the 2004 Local Elections Green Party Candidate Tony McDermott who was elected in the Terenure Rathfarnham ward.
Tony McDermott also ran in the 2007 General Election in Dublin South Central polling well but not enough to win a seat.
He failed to hold his Council seat in 2009.

The comment “He failed to hold his Council seat in 2009.” on this page:
https://irishelectionliterature.wordpress.com/2010/04/07/tony-mcdermott-green-party-2004-le-terenure-rathfarnham/
is not strictly true. More accurate is: “In 2009 he moved from South Dublin to the Crumlin / Kimmage ward in Dublin City and failed to win a seat in the slimmed down 4 seater.”
Apologies Tony….. I’ll correct it.
