If the weather is very bad (or very good) on Polling Day, then I think that 'Leave' will just win. Like Jackdaw, nothing on Earth would stop me reaching that polling booth, I care so much for my country and grandchildren.
It's early days, however, Dave's leaflet was a mistake, the EU is flexing its muscles over international companies' taxation and their plans for 'harmonisation' are dribbling through despite their attempts to keep things under cover until after the referendum. Much depends on 'Events, dear boy, events!' But I'm going to have a small flutter (I'm not a gambler) on 'Leave'.
