You've led a very sheltered life John. :0)

I believe it is worse in the West and the central belt, a hangover from the days that the Labour mafia held power through its use and the works were controlled by Unionist bosses,

On my reckoning, at least 5% voted primarily on sectarian lines, another 5% on promises of Devo- Max which will never be made good.
The well off pensioners, featherbedded by the Scottish Govt voted 75% NO.
The young folks voted 75% YES.....and they are the future.
