With Cable's and Clegg’s personal ratings being so high, the trick is to play the ball not the man. Ken Clarke and George Osborne achieved that at this morning’s press conference. Clarke said: “(Nick Clegg’s father was) a very nice, very wise guy, he was a very successful City guy, but he wasn’t a flashy guy... he was a Tory. It would have been better if Nick had stuck to the political principles of his father. (Nick Clegg) must regret going into the strange wastelands of Liberal Democrat politics.” He added that whilst he agreed with “70 percent” of Vince Cable’s analysis on the financial collapse, Cable’s solutions left him “bewildered”.

Fleet Street resounds to just one gag today: every ash cloud has its silver lining. Tony Blair is marooned in the Middle East and won’t be plugging his memoirs at this week’s London Book Fair. I wonder if he’ll adopt a few Semitic shrugs to accompany the gauche Cary Grant accent. Still, we must wait longer for the author of Blairism’s recollections. Blair may have degraded into self-caricature, but his premiership deserves a literary legacy. It was dominated by thrilling conflicting narratives. Blair’s obvious political skill was matched by convictions over which the three parties still battle: public service reform, choice and eradicating entrenched social divisions to name but three.

The FT’s Jim Pickard writes: ‘Cameron will be cursing the order of the debates. He’d much prefer to be attacking Nick Clegg on domestic issues than foreign affairs on Thursday.’ I’m not so sure. Foreign Policy is the arena where the Tories are concrete, populist and accessible. The same is not true for the Lib Dems. Along with Iain Martin and John Rentoul, Pete noted that Ed Davey is vague on the Lib Dem Trident replacement policy. Davey's vague with good reason: the policy is hopelessly confused. The manifesto says: ‘Rule out the like-for-like replacement of the Trident nuclear weapons system.

The consensus is that David Cameron made a mess of last night’s TV debate. And whilst he wasn’t bad, he certainly wasn’t good, especially to watch. In a post over at Cappuccino Culture, I make the point that Cameron was the most static and soulless feature of a static and soulless piece of television. Undoubtedly the Tories' greatest presentational asset, his subdued performance is inexplicable. Whilst there is no cause for panic the Tories are rightly trying to regain the initiative. Gary Barlow’s appearance with Cameron at a school this morning didn’t relight Dave’s, or anyone else's, fire.

Sorry is the hardest word and Gordon Brown stil hasn’t said it. But, everyday brings surprises. His ‘admission’ about his errors is the first time I’ve ever agreed with his economic analysis. In short, even Brown knows he’s not what he’s cracked up to be. Making such an admission at this stage of the election cycle is extraordinary. The intention may have been to make Brown look human. In which case, he’s succeeded, but to his detriment. Brown looks Biblically fallible. Labour’s campaign rests on one deduction. Gordon Brown built an era of prosperity; then Gordon Brown saved the country from a recession that originated in America; therefore Gordon Brown is the man to lead the country back to prosperity.

The Tories’ Invitation to join the Government was never going to dwell on defence. (You can listen to the brief chapter on defence here.)  But that doesn’t mean defence isn’t an election issue. It is, and it's one that the Tories will win. Brown’s defence record is abysmal even by his standards. Former service chiefs have described how Brown ‘guillotined’ defence budgets whilst fighting two wars, and field commanders in Afghanistan have made constant reference to equipment shortages. These accusations were corroborated by facts that Brown then tried to distort before a public inquiry. That’s not all.

Chris Grayling, the Shadow Home Secretary and former attack dog, seems to have been cast into outer darkness. As with Oliver Letwin’s disappearing act in the 2001, Labour is toasting this unofficial scalp. Denis MacShane has been adding poison to the potion this morning. The Tories are paying a heavy price for Grayling’s B&B gaffe, but it’s self-inflicted. Grayling’s comments were cackhanded and I think he is wrong, but they were nowhere near as controversial as was claimed – he was seeking a clarification of the law, not calling for Sandi Toksvig to be lynched. I doubt Grayling will be Home Secretary but such a senior Shadow minister can’t hide away for ever.

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.

Well, now we know. Charlie Whelan enjoys the liberty of Westminster at the invitation of the parliamentary Labour party. Guido points out that it’s highly unlikely Whelan isn’t officially connected to Labour’s campaign. Labour tried to keep all this quiet, attempting to avert an ‘affluence for influence’ story that might undermine Brown’s attempt to turn the election into a referendum on Lord Ashcroft. However, though this should prove bad news for Labour, these stories have little impact outside Westminster. Neither the Ashcroft scandal nor previous Whelan sagas moved the polls.
