Cameron is set to return to Westminster tomorrow a New Man. First blue turned into green then Mr Angry. But now the rebranded Tory leader is set to be the new statesman, positioning himself for the prize of the premiership. No wonder New Labour is running scared.
For Cameron's Conservatives it has been a game of two halves but the trick has always been whether he could pull it off with the voters.
The uphill task was to first turn round the Tories into a Party that could be 'elected' . And that was no mean feat as taunts that he was just another heir-to-Blair and a Thatcher's boy haunted him.
After the 2005 election defeat, the Orange Party, believed it would take a decade and a couple of general elections for the Tories to begin to gain ground.
But even with no general election on the horizon, Cameron had it easy, as he rebranded the Party in the eyes of the electorate.
Misguided PR stunts made Cameron look a fool but Brown made his fatal mistake, bottling a general election in 2007. Cameron would have been out on his ears. But Brown didn't and the rest will be history.
To Cameron's credit and relief of the Tory big guns, what emerged was a 'government-in-waiting'. And after half-time the second half could now begin.
A new Tory Cameron came out fighting but time and again opinion polls and local election results showed a vote against New Labour rather than a vote for the Tories. A true Labour revolt was no match for the powerful New Labour elite.
It was a collapse of New Labour rather any great new enthusiasm for Cameron's new kids on the block.
Peter Oborne writing in yesterday's Mail believes this second stage of Cameron's leadership has now run its course:
"The truth is that Cameron was always destined to reinvigorate his job - his family tragedy coincidentally placing a sad punctuation mark at the end of the second phase of his leadership.
"The other Cameron was simply leader of the Opposition. But the new Cameron will present himself as a prospective prime minister - a more mature, sombre and tough individual than the plausible charmer of the past few years."
The Orange Party will miss Mr Angry coming over all hot and bothered as he squared up to Brown and the mess of a festering New Labour government.
But Cameron, the new statesman, capable of dealing with a monumental economic crisis, will require a change of substance as well as style.
Backing Brown's disastrous economic bullshit that the economy was in good shape, despite the warnings, wasn't fatal for the Tories but it did teach Cameron some harsh lessons. Being honest with voters is always the best policy in the long-run, as long that captures public mood.
Even now, the Tories seem to be backing the government, matching spending on health, welfare, education and defence, when the economy is so bad some of these grand commitments will have to go by the board. Voters need to know where they stand.
Brown's government is set for another pre-election spending spree in next month's delayed budget on the back of reckless borrowing and the short-term 'printing money' fix.
Cameron cannot ignore the fact that he will, very soon, take over a country on its beam ends.
The deluded prime minister and his hapless chancellor remain in denial about the severity of the situation. That would force them to own up to their part in the downfall, as they carrying on spending like there's no tomorrow. For them, there is no tomorrow.
But Cameron is on the horns of a dilemma. Does he come clean and admit the true devastating scale of the crisis and risk being accused of talking down the sorry state of the economy and the country to make political capital?
A different kind of country will no doubt emerge once the recession depression finally lifts and voters have a right to know exactly what kind of public services and lavish overseas spending commitments will have to go.
Brown is passing on a disaster waiting to happen but Cameron still has to give voters a strong and positive reason to vote Conservative.
Cameron cannot just wander into office, do a Brown and Darling and bury his head in the sand, pretending that he will not have to carry out brutal cuts to state spending.
He has to spell out the sheer magnitude of the problem without appearing to gloat in all the misery.
But it is essential that he does spell out the stark truth. Voters are wised up to the economy and can see through the lies, spin and deceit which has built up over the years.
The brutal fact for the dying New Labour brand is that the Tories really don't have to do all that much at all.
Clegg's fine words to conference reveal the Blair-boy he really is underneath and, for the LibDems, only the economic oracle Cable is propping up the Party and saving it from oblivion.
The Bearded One reported in today's Sunday Times has once again delivered a sermon from the pulpit, slating Brown and the government. Attacking New Labour rather than individual greed, the Archbishop of Canterbury blamed the financial crisis on a "spectacular failure of responsibility by the government."
When even God deserts New Labour you know it's time to call it a day.
And Cameron may not have much time to convince voters, with ITN's Tom Bradbury blowing the gaffe on Brown's air-rage, revealing a man who has lost the plot.
The men in grey cloth-caps may have to finally force Brown to make that call for the good of his health, their seats and country.
