Does it pay to be mendacious?

Lying is a politician’s occupational hazard. The Independent on Sunday has published a Com Res poll confirming that truism. The majority of voters do not believe that David Cameron and Gordon Brown are being honest about how they will tackle the deficit. We voters resent being taken for fools. If Brown and Cameron are being disingenuous about the economy, the honest Sage of Twickenham benefits – the Liberals are storming the marginals, a hung parliament is odds-on according to some pollsters.

Is Vince Cable honest about reducing the deficit? Emphatically not. One minute he’s against a VAT rise, but refuses to rule it out the next. He’s in favour of unilateral charges on banks, but not if they fund a tax break for some married couples. The Liberal Democrat’s peculiar hypocrisy is that they demand an even wicket but scuff-up the one that already exists.
