Centrism - an idea whose time has come?

Key
the gray line is number of seats held by LibDems
The  blue line is the percentage vote share of the LibDems
The orange line is the absolute votes (in millions)
And, just for fun, that other bunch of Centrists, the Independent Group are in red, who went from 0 to 6 seats by splitting from their parties. And just as quickly plummeted to 0 seats, once they were forced to fight and defend their seats.

As the elections for the Labour Party hot up to choose Corbyn's successor, there will be enormous pressure from Blairites to 'return to the centre', as the only way to become electable.

If you are faced with this bullshit, just ask them to explain this chart: Actual results from the last 7 elections for the LibDems, the archetypal 'centrists'.

As we can see, Centrism is the least popular political current in Britain today. Corbyn's red-blooded socialist manifesto got more than 10 million votes, better than 'New Labour' in 2005, 2010, 2015. And, while the votes for Labour have improved overall, so have the Tories.

That elusive 'centre ground', which is, we are told, the key to becoming popular again, does not seem to be all that popular.

The country's desire for 'centrism', 'moderate', 'Blairite' has vanished in a puff of logic.
