I'm not predicting - I fear the hex...but FWIW, Michael Portillo, who whatever you think of him is a pretty sharp political brain, said a few weeks ago that the big nightmare scenario for innies was a low turnout - jaw-frothing outies straining to stick it to Johnnie Foreigner being less likely to simply let it slide than the rather more lukewarm innies. The tipping point, if I remember rightly, was 65% turnout. Lower, and the outties get it; higher, and remainers take the day. Sounded plausible to me. I suspect the predictions above of 80% turnout give or take will prove wide of the mark. I'd settle for 70...
