Does a bear defecate in the woods. Using devolution with a d'Hondt system to put the genie of nationalism back in the bottle worked about as well for Labour as posle Tita, Tito (after Tito, Tito) worked for the Yugoslav League of Communists. Suspect what the other parties also very much regret is giving the SNP a crack at it as a minority government in 2007. Hand the irrational nat nuts enough rope and they will hang themselves was no doubt the mentality but instead by being more competent than Labour (not exactly difficult) the SNP and by extension further constitutional change lost a lot of the fear factor that had previously been involved for a sizable chunk of the electorate.
