KEVIN Rudd says he's a changed man since being dumped by his own party and spending years in the political wilderness.
There are some that don't buy it - including within his own party.
But most Labor MPs are resigned to the fact that the former diplomat remains Labor's only hope of beating the LNP and Tony Abbott.
Certainly, recent opinion polls bear testimony to that.
Mr Rudd is well known for working extremely hard - and expecting senior public servants and ministerial colleagues to do the same.
In his first stint as PM, he had some major blunders, including his policies on refugees, which recently he reversed with the controversial PNG solution.
It has been seen by many as more right wing than Tony Abbott would have ever dared.
The PM was also recently forced to apologise for the deaths of young men involved in the government's bungled home insulation scheme.
Mr Rudd has been known for his outbursts of anger, including repeatedly dropping the f-bomb as he prepared to do a video message in Mandarin.
But in recent times, he has promised a more gentle - and conciliatory Kevin - moving away from the style he was well known for when he was chief of staff to former Queensland Premier Wayne Goss and later the state's top bureaucrat.
He's also had plenty of changes of heart - including on the subject of gay marriage - putting him at odds with his sister, a devout Christian.
His brother, Greg Rudd, is running as an Independent in the Senate, and admits he will only vote for Kevin out of family loyalty.
Mr Rudd's personal style will be the subject of plenty of attack ads during the 2013 federal election campaign.
We can expect to see clips of Wayne Swan describing his former Nambour High colleague's tenure as 'dysfunctional' and Tony Burke describing his office paralysed by chaos.
But watch Kevin Rudd in public and there's no doubting his popularity.
He is swarmed by school students like a rock star and even police line up to be photographed with the high flying 'Kevin 747'
One of Mr Rudd's proudest achievements is the apology to the Stolen Generations as well as ratifying the Kyoto protocol.
But with jobs and the economy the big focus - as well as rising living costs - talk of climate change and carbon tax is about as popular as opening Australia's doors to asylum seekers.
