That is the next step the leftists are moving toward throughout the West. They try to make it so the election itself is illegitimate because of some bugaboo they invent. Examples include “racism,” “foreign interference,” “illegal influence,” “hate mongering,” etc.
We are moving toward a future where the left no longer tolerates elections that thwart their will. Virtually anything that leans conservative in the future will be labelled racist, hate speech, unjust, etc. and thus illegitimate.
I see the Labour MPs now blaming Corbyn. They probably have wanted to get rid of him for a long time, but just couldn’t before. Of course doesn’t fix the underlying problem of broken leadership elections system.
