People like DCahill are known on a wider national scale with these more academic "intellectual" issues concerning EU and the intricacies involved.They'll get votes. Delores Cahill got a very impressive vote haul despite the shambles of having no party to stand for. Unlike the NP and ACI I think they have a good pool of people to run for the party too.
This translates into votes when it comes to EU voting. However unless she is well-known locally in her local constituency, this does not translate well on that level.
On the General Elections, what counts is people who are well-known or simply known to be a local who has the interests of the locals at heart.
This is what the NP have in spades, and that is what they have been focussing on.....grassroots membership with local men and women representing their own local places. This is the key ingredient to getting Dáil power, it takes time, and it starts off with getting local council seats or if skipping that, having put in the work and time to get the locals knowing your about and have been looking out for them and will look out for them if elected.
NP are well placed to do this, but must make sure real community work and representation is being done from yesterday right up to GE time and beyond.
