If it helps, I wil not vote PSF or PBP under any circumstances. If I think I can frustrate one or other candidates running for them, I will vote "for decent candidates". That limits my choice severely."Blocking Vote" = "Various Reasons"- fair play.
I would not vote NP types except as a massive protest.
Imagine we are all 12 year old school boys today. We have to pick an EPL team to support? Winners like Man City? Or the Broad Black West Brummers Warfields supported long ago. Say we want to support a Dublin team. Bohs and their Antifa dregs? We just want a night out but we have to have the Antifa crap rammed down our throats.
They have taken over the shop and expelled the rightful owners. We must now scratch our heads and think again. We can try to build a new group like the NP or try the cuckoo approach (hello Aontú) but new parties find it hard here and the dispossessed like RSF find it no easier. Fianna Fail, Dev's comely maiden party, are now promoting gay saunas. But there is always Fine Gael.
