Regarding the recent discussions on a border poll... As it stands right now, I would vote no on a border poll for the simple fact there is no plan and there is no discussions on coming up with a plan outside of vague and non binding think tank discussion. I think back the GFA referendum. We knew what we were voting on, what institutions would be created, how power sharing would work etc. No they didnt have every detail ironed out but there was a plan.
For a border poll it would be irresponsible to just have a yes/no option without know what a yes would mean. I would compare it to holding the Brexit vote and then having to make up the plan on the fly.
Issues that need an answer would be...
1: Administrative model - Will the NIA be dissolved and its functions folding into the Oireachtas or will the North maintain a devolved administration
2: What amendments are needed for the Constitution or indeed will we need a fully new Constitution
3: Rights and Protections for Unionist Community - Establishing explicit legal guarantees for British identity, including flags, symbols, and continued recognition of British citizenship for those who want it. And yes the national flag, anthem etc needs to be on the table.
4: Debt Transfer: How will the debt of the North currently shouldered by the UK, transfer to the Irish state. This includes pensions.
5: Economic Alignment How will we synchronising two different taxation systems, currencies, and public sector pay scales
6: Merging of healthcare (NHS), Education (Leaving cert or A levels), policing and justice (PSNI and the Gardai and what courts systems will be used)
7: EU (re)integration: Admittedly the EU has already said a united Ireland would be in the EU but phasing that back into the North
8: Military: the neutrality issue and the fact the North by virtue of the UK is in NATO
9: Criteria for a vote and who can actually vote... age, residency etc
