I am a voice for change. The people in Dublin West have had the same old, same old... I will give them the opportunity to register their disappointment with the current politicians.

If elected in Dublin West I would love to be the Minister for Housing or Health, because we don't have a housing problem so much in Donegal as in Dublin.

I would like to be a voice for really helping to put together a pro-business government to help the people of Ireland... I would want to really make sure we have a pro-business coalition tackling the problem of Brexit.
