Not sure if any this side of the pond could be bothered. Enthusiasm for anything has been killed by 1000 cuts.
I voted say in, and now feel I would vote out just to be bloody minded. I am past caring.
The politicians all lie so none can make subjective decisions, so most will vote in their entrenched positions. London "in" the North out. The north will probably vote out stronger than before if anything imho. There is no downside for them. Same with the old... still out... there are perhaps a few less oldies if it were run again.
