Wednesday's disaster means Labour ends the week having taken 10 strides forward and nine steps back.
Goff will pick himself up and carry on regardless. He is displaying the born-again zeal of the religious convert. He is drawing fresh inspiration and energy from his new self-designated role as the politician willing to make the "tough" decisions for the good of the country.
This may take some swallowing by voters coming from someone who was party to the messy business of government for so long.
Many will simply see Goff's potentially suicidal decision to be the purveyor of unpopular, yet necessary policies as the last desperate act of someone whose rapport with the electorate is so low that he has to shock just to get noticed.
If - as the polls suggest with unwavering assurance - Labour has no show, Goff will draw solace that he fought his last battle doing the right thing and at least getting future pension policy and a capital gains tax up for debate.
Wearing this mantle also gives Goff occupation of the high ground, however. Suddenly, he has discovered how to belittle the Prime Minister without looking petty.
And Goff has not held back from attacking Key. This has made utter nonsense of the refrain from Labour's strategists that the party's campaign would focus on policy not personality because Goff could not hope to win a popularity contest with John Key.
Maybe not. And Goff has talked policy. But he has used that policy to round on Key at every opportunity. He has no choice. Key is Labour's nemesis. He is the difference between Labour potentially coming close to being in a position to form the next Government and it wallowing in its current agony.
Turning its back on the traditional presidential campaign was never going to last beyond five minutes. Goff's resurrection has given Labour every reason to embrace the presidential campaign even more.
