The government will debate and most likely introduce new rules for a presidential election this week. The new rules mean that one additional option is added to the nomination process: In future a candidate can also be nominated by getting 10 000 signatures from supporters.
Not really relevant for another 7 years, but a good idea.
If they now change the rule that you have to be an Irish citizen to apply, I might go for it myself the next time. :-)))
