I don't believe they could rig the vote with almost a 10% margin.
Even if they did rig the vote, it would had been minimal and the result would be the same. Then again, even my paper had no identification number. Usually they would stamp it and score your name off the register. When I declared my name the woman just gave me a random paper and didn't score off my name. After I voted, I folded it and noticed that it was blank on the back. Legally those papers would have been dismissed and unregistered as spoiled, if the polling counting officers wished to do so. To top that off, my local constituency had a lower turnout than expected. I asked 7 friends about this, 4 of them that voted SNP in the previous election had blank ballots and 2 of them who had voted Labour had normal ballots. The last one voted SNP but had a normal ballot. I just found it all a bit weird.
But I'd rather we just take defeat as it is; defeat. We will focus on the present and the future. It is only a matter of time now before the Union ends, and it will come sooner than you may think.
