Unlike many, I am perhaps thinking of things deeper, and blacker, than the short-term economic impact or what it means for Britain's levels of immigration (very little, according to the leaders of the Leave campaign themselves).
I wrote this piece for Labour Uncut last Wednesday - the day before the referendum - and, given the delight which has greeted Britain's exit in places such as Moscow, it seems somehow now all the more relevant.
The decision Britain will make tomorrow is clearly a big one. Perhaps truly the most significant of our lifetimes, in terms of its strategic direction of travel as a country and the way the 21st century will shape up for us.
A decision in favour of Brexit will inevitably have short-term impacts. Some of them, such as a potential drop in sterling for exporters, may even be positive. But some vital, long-term effects are likely to be about Britain’s place in the world; its geopolitical power, if you like.
These are difficult-to-gauge, but nevertheless important, effects which are largely drowned out in the current debate by the bread-and-butter arguments about trade or immigration. Or “sovereignty”, that largely meaningless word currently being flogged to death.
Which would be fine, if we lived in a world full of stability, free of threats. Or even such a Europe.
We do not.
