Surely having a foot in both camps ie remaining in the customs union and being part of the UK could be potentially a very lucrative position for Northern Ireland to be.
Amazes me that the DUP are still so tied up in their old rhetoric that they can't see a good thing when it is hitting them square in the face.
I wonder how those elements in its support who are in business and would stand for economic co-operation (staying within the customs union, embracing elements of the single market) but draw the line at Constitutional drift from the UK will react to such offers? Less 'staunch' than their leadership I'd imagine.
The DUP leadership are possibly shackled from accepting compromise by forces to its right who could make inroads on their votes if the whiff of a sell out was at large.
When the parties negotiating Brexit start up again soon it'll be merely another form of words to present the same idea of a different type of withdrawal for the EU by NI. There can be no other outcome as only when the RoI are happy can any deal be agreed.
Best thing all round is to have a general election which sees a single party majority outcome.
