I guess it'll be a bit like jumping out of the democratic deficit straight into the democratic deficit.
There will be an issue of size, of course. Scotland currently has her own government and not inconsiderable autonomy, as well as 59 MPs (out of a total of 650) to represent her constituencies in Westminster, which in comparison with England constitutes something of a striking democratic surplus.
Should she part company with the UK and rejoin the EU she will replace that enviable state of democratic representation with perhaps 6 MEPs out of a total of 700 odd, who will sit only in the EU's legislative body signing off Commission directives, and of course, having lunch, whilst her government will be relegated to the status of a District Council, organising the bus timetables and the rubbish collections.
