The Scottish Parliament may not be perfect, but it's a hell of a lot more practical than Westminster. Government and politicians aside for a minute, Holyrood is a better parliament. In terms of logistics, Holyrood is centuries ahead of Westminster (with automatic voting technology meaning a division can take only a few seconds, rather than the twenty minutes it takes in London). And the rabble of Westminster is utterly embarrassing.
In terms of the actual politicians, I look at the Labour lot in London, and compare them to the three administrations up here (two Labour and an SNP). None of the three are perfect, but all of them seem to have done a lot more than Labour in London at the time. And the delivery of some pioneering legislation, such as world-leading climate change legislation, the smoking ban and the breastfeeding laws, years ahead of Westminster and in a fraction of the time.
Scotland's Parliament is something I am genuinely proud of. There are faults with it; to say it got off to a shaky start is the biggest understatement of last century. But it does deliver, and it's considerably better value for money than the politicians in Westminster.
