I've been about as EU-philic as you get on this site at times -- but that's tended to be more about the principle than the practice. In practice, lately, it's not working very well. Thing is that my answer to that -- more integration, not less -- is precisely the opposite of most other people's, and in particular the opposite of Cameron's proposed renegotiations.
2017 remains a way off yet and I still feel it's likely that the devil we know will prevail, and we'll end up staying. Rather like the Scottish Independence movement, though, Brexit will find it easier to gain momentum.
Speaking of Scottish Independence, the EU issue could mix in with that too still and I'm a little anxious that if there is a split decision on whether to stay or go that things will boil over between Scottish and English. There is no reason for them to, in theory -- democracy has to have a loser -- but in practice I doubt it will work out so easily!
I can't say I'm looking forward to the referendum, anyway. Too much riding on it.
