Lachlan Harris, former chief press press secretary to Kevin Rudd, agrees: ''Everyone makes mistakes in the heat of the battle - the big mistake for me was the initial defensive reaction. ''Politics is not a statistical game, it's an emotional game. It was a dopey remark that should have been realised straight away and corrected.'' The first rule of backflips, Harris says, is you have to make them as quickly as possible. This would have helped prevent damaging follow-up stories – including tabloid splashes on the "chauffeur-driven" Treasurer's supposedly lavish spending on taxpayer-funded travel. In fact, at $26,256, Mr Hockey’s car entitlements for the past six months of 2013 were less than half that of fellow senior ministers Warren Truss, Christopher Pyne and Scott Morrison. Wayne Swan spent twice as much on car travel in his last six months as treasurer. Communications consultant Jane Caro says the problem with Hockey's gaffe was that it reinforced beliefs he is out of touch with low-income earners - an image personified by him smoking a cigar outside Parliament House.

In his apology on 2GB on Friday, Hockey used the words ''sorry'' and ''apologise'' eight times - and his voice carried genuine emotion. ''All of my life I have fought for and tried to help the most disadvantaged people in the community,'' he said. ''For there to be some suggestion that I have evil in my heart when it comes to the most disadvantaged people in the community is upsetting.'' But Caro says the apology ''felt too much about him rather than the people who are affected''. ''People don't think he's evil; they think he doesn't understand what life is like for those on low incomes.''

The gaffe has sparked debate within the Liberal Party about the quality of advice Hockey is receiving following the departure of three of his most senior advisers since the federal election. ''There definitely needs to be a toughening up of the political process to make sure these things don't happen,'' a Liberal insider said. ''There needs to be less ideology, less fighting about nothing and more experienced operators in the offices.'' Harris says Hockey can recover from the gaffe because there is no sense of dishonesty or impropriety about him. Ralph says Hockey's best shot at redemption is passing some big savings measures. ''There's always a temptation to overcompensate after an image crisis like this, and be seen dishing out meals at soup kitchens or caught handing out blankets to the homeless, but the worst thing he could do would be alter his behaviour.

''Time and authenticity are on his side, so he should simply tough it out and focus on fixing our overspending.'' Given the unruly nature of the crossbench, of course, that's no easy task. And Hockey's budget itself is unpopular. A poll of 1400 women by cosmetic company Heat found only 13 per cent of respondents felt positively about the budget while 62 per cent felt negative and 25 per cent indifferent. Seventy per cent felt the budget would negatively affect their standard of living. Hockey's howlers

May 15 Accused of being patronising when he compares the Medicare co-payment to beers and cigarettes: “One of the things that quite astounds me is some people are screaming about a $7 co-payment. You can spend just over $3 on a middy of beer, so that’s two middies of beer to go into the doctor.”

Warns he is ready to bypass Parliament if Labor and the Greens oppose budget savings, sparking accusations the government plans a new round of tough spending cuts.
