Until someone brings to the table the processes that protects pensions, and not charging for doctor and hospital appointments( got alot as not well). The gap in pay differences north and south, the increased cost of food prices between both. Until the persons looking a border poll answer how these issues are to be resolved, before a poll, they are wasting their time. Nobody gona go down a route like the leaving the EU vote, as it was obvious nobody knew what they were voting for. A border poll vote blindly on the basis of just a United Ireland ain't gona cut the mustard anymore with people. Bring forward a proper basis and plan why it is better for united Ireland, instead of the usual bullshit about unity. A border poll in the morning wouldn't even be close, and in turn affect delay another vote to years down the line.
If a border poll is called now, as per the GFA there must be one held every 7 years thereafter.
Brexit won't be subject to a second ref because the Tories are afraid of a rejection and paralysis.
An unplanned SF UI would be a total clusterfuck economically. Why would anyone in the South vote for it 7 years later?
The only way to do it is properly.
