Agreed. But the actual numbers that voted for Corbyn-led Labour in 2019 are less catastrophic when stripped of the rhetoric of “landslides” (10.2 million votes for Labour and 13.9 for Tories). The first past the post system we have exaggerated a Tory win when a majority of voters actually voted against the Tories (57% of the vote).

It can’t be ignored that the Labour Right and party machine were actively undermining Corbyn at the time. There were even party officials who told each other they’d prefer a Tory win rather than Corbyn as PM.

Also can’t be ignored that Brexit had a distorting effect on the 2019 election and Corbyn handled it disgracefully.
