The lesson from that phenomenal result - Corbyn connects.
Certainly he does in the Labour party where six in ten members backed him as their first choice.
That is a call for a different way of doing politics and for a different Labour Party.
A mandate like that is unassailable from within and resistant to the many setbacks and traps external opponents will put in the way of the new Labour leader.
It’s clear now that this summer politics in the left in Britain has undergone the same transformation as the nationalist politics in Scotland experienced last year.
Defeat has spurred political activists to express their core values, nationalism in Scotland, socialism within the Labour party.
The anti-politics surge that gifted the SNP with over 100,000 members after the referendum has left Labour with over 500,000 across the UK.
But be careful, the SNP membership still outnumbers Labour by five to one in Scotland.
Will Jeremy Corbyn’s anti-establishment credentials, his principled socialism and left-wing values connect with voters better than Nicola Strugeon’s assured, groomed and polished nationalist operation?
Although amazed by the result Corbyn looks like taking leadership in same straight-talking style as he won the contest with.
Mind you, it was noticeable that his powerful victory speech was aimed at the Labour support in the hall and not at the TV nation looking in who he must introduce himself to connect to with the same vigour.
In Scotland the test of Corbynism will be if his policies pull back votes from the SNP.
If they do not then what is happening in Scotland is not about politics at all, it is all about identity.
