It seems the Scottish Nationalists have invented another "populist" idea to lower the voting age to 16. I would wager it's just another fight to pick with Westminster (because any legislation altering the voting age must be decided in the UK parliament). When this crackpot idea falls flat, the Nationalists can whine about Westminster foiling their clever policies.
Sorry teenies, but most 16 and 17 year-olds are just not clued up enough to vote. Of course, most people over the age of 18 aren't clued up enough to vote either, but the law says they are allowed to so we just have to put up with it. When I become Supreme World Leader, anyone who bases their political and world views on what The Sun or The Daily Mail says will be stripped of their civic rights.
