Have the forgotten voters of Glasgow East triggered a political earthquake?

You don’t mean a thing if your seat’s not a swing – that is the rule which governs Britain’s constituency voting system. Its worst aspect is the emergence of modern day rotten boroughs, where no mainstream party votes. The more I hear from Glasgow, the more likely it looks that the forgotten voters of Glasgow East might – just might – trigger that political earthquake. If it does, it will be for a simple reason: it’s difficult for Labour to turn out your voters if you have never really bothered to find out who they are, or where they live. Difficult to find out at short notice, if your grassroots operation has atrophied. Word tonight is the SNP has canvassed far better, with its highly motivated activists determined to make this the most significant by-election since Hamilton East. Stay tuned.
