The Liberal Democrats failure to take power has fuck all to do with constituency boundaries, and everything to do with the fact that they're unelectable kiddy-fiddlers, poofters and alcoholics.
Scotland can't be devolved, or we'll just end up stuck to a poverty-stricken wasteland and even more of the piss-stinking bastards will end up in London begging for change. What we will hopefully do when the rightful party get into power is change the rules so that the Scotch MPs can't vote on issues that have been devolved, like education, welfare and health, in England. Obviously Labour have no interest in doing that, since it would fuck whatever tiny majority they have left.
