'Blair was up against a stagnant Tory government, plus he moved to the centre, not further left, the fact blairite is used as a slur within momentum makes the comparison void, no?'
I am not in Momentum so I don't care what they say. Blair was right for the time - 1997 - which is why and I and millions of Tories switched and delivered a landslide victory for him. After 18 years, Labour finally won because Tory voters had had enough of the Tories, no other reason.
Blair went centre then because it was the right thing to do at the time, but it is no longer the right thing to do because Blairism is now a dirty word among Labour, Tory and LibDem voters. The only people who like Blairism are Cameron and the Etonians.
The centre has collapsed for a reason, the people no longer want it, they want change which is why the 172 centrists got so heavily defeated by the left wing former outcast and laughing stock, Jeremy Corbyn, because no one is laughing any more because he is now more in tune with the times and the people.
'but if you haemorrhage long standing members in the mean time it negates the point. '
We have witnessed a huge change, a huge disruption. The 172 don't like it and are struggling to adapt to it as are councillors and party old guard, but they will all have to accept that we are in a new era, the old days are over, Blair's speeches and Brown's stage strutting don't cut it any more, so older members will have to adapt to the real new Labour which is back to real old Labour because where else will they go. Will they be like George H W Bush and vote for Clinton instead of Trump because the centre has collapsed or will they work with the new reality or will they try to split and for a new centre? Times have changed, if they try to form a centre, they will be defeated because Tim Farron and the centre has collapsed, people now want real change, no more spin.
