Scotland was a labour stronghold for a very very long time. Pretty much because everyone voted as they and their families always had. When we got devolution people started to notice that nothing changed whether it was red or blue. Astonishingly, people decided on neither and that's how the SNP got in. They have their own faults is true but it's nice to have a change from one or the other of the old guard.

Lol, obvs it's a little more complicated than that :0D
