"A week ago, the first leadership debate transformed the general election campaign.Whether we like it or not, the X Factor politics of the leaders' TV performances will play a significant role in the selection of our next government.So it was a matter of some concern that ten per cent of the electorate could change their views so dramatically in the space of an hour-and-a-half, and that Nick Clegg and the Liberal Democrats could emerge as the apparent winners of that debate with the public learning so little of their policies and values.Over the last week, this newspaper has tried to rectify that failing, and we continue today with our examination of what the Liberals really stand for. .....It's almost beyond satire. Yesterday, Peter Mandelson, aka the Prince of Darkness, attacked four newspapers, including this one, who have turned the spotlight on Nick Clegg, for 'pushing the smear button'.This from a man who perfected Labour's dark arts of smears and political assassination.Let it be said loud and clear that 'Lord' Mandelson has been one of the most malign forces in recent political life. It is his predeliction for spin and mendacity that did so much damage to his own party and to electors' trust in politicians.He's still at it, of course, by talking up Nick Clegg. Knowing that Mr Brown is going to lose, he is trying to engineer a LibLab pact after the election, to keep his party in power, and install his protege David Miliband as Labour's new leader."
