There may yet be a joker in the pack tonight, as there was in the 1997 Welsh devolution referendum when the BBC briefly forecast No as the winners, only for Carmarthenshire to completely buck the national trend and carry Yes over the line with an overwhelming vote. But at the moment, Leave appear to be the more likely winners. We heard strong indications from Brian Taylor earlier (at a point when it still looked like Remain would coast to victory) that in the event of a vote to withdraw, Nicola Sturgeon would at least very quickly demand that Westminster gives Scotland the power to hold an early referendum if it so chooses.
I don't know about the rest of you, but I hope there's no backtracking on that plan - I think that's absolutely what's got to happen. Voters were told in 2014 that if they voted No, they were voting to remain EU citizens. They duly voted No. Today, Scotland voted by a more than 'decisive' margin (to use the approved BBC word for anything north of 54%) to remain EU citizens. We must now be allowed to remain EU citizens. If that doesn't happen, it would be a democratic outrage - it's as simple as that.
UPDATE : I should point out that Remain are still the favourites on Betfair. I can't say I remotely understand that given the numbers we're all looking at, but perhaps I'm missing something and the scenario I've just outlined isn't likely to happen after all.
UPDATE II : I'll tell you another thing about what's happening tonight, and I know some of you don't want to hear this - it absolutely obliterates the myth that Yes would need to have a strong lead in the polls before it would have any chance of winning an independence referendum. There isn't always a reversion to the status quo in constitutional referendums, and that must now be abundantly clear.
