This is not to say I concur with the exit polls entirely, only if Britain has really excelled itself in tactical voting this time round can they be true. Lots of conservatives vote autonomously, and most over the age of fifty will do that regardless of the sky being on fire. Starmer is a wildly unpopular and mistrusted leader of the labour party. This is about the youngun's and genz punishing Tories. Which they will.
So a landslide yes, but not a truly historic one. It'll be less extreme.
