A often used technique in political campaigning is to build a fake website, in your opponent's name or something close, and then use it to undermine that opponent. While it is fairly obvious that the website is the creation of the opposition, it always has the veneer of being unofficial and can be denied if pushed. WebCabinet is a dig at the Conservatives, it has the shape of a chat room and in it leading Conservatives are supposedly chatting candidly about the way they are deceiving the public by offering tax cuts (see the pic you get the idea).
The odd thing is that it is actually embedded within Labour's official website with logo and everything and invites visitor to get involved. Now it can be applauded for being an honest attack, but it also links it directly to the party. It can also be seen as somewhat childish, perhaps not something we would want the party of government to produce, so perhaps an own goal. Whatever the verdict, depending on if it gets any airing in the media, it proves that Labour is proving the believe that old adage that the best means of attack is defence is correct, however should a government defend itself by purely by making its case or is this an appropriate weapon in the political campaigner's arsenal? In an age of cynicism it may hit the right chord or it might turn voters away from politics all together as both sides increase their attacks; the academic jury is out.
