As you keep pointing out (and as I also mentioned)

The system is to vote for the party. Many people vote for the person, not just the party

In many places where politics is discussed in public, the discussion is often of the leaders, not the parties - “well, BoJo is a geezer, innit? Top bloke!” or “Starmer is a boring git, wouldn’t share a pint with ‘im” or “Corbyn will send us back to the 70’s” or “Blair is such a breath of fresh air” or “Cameron is such a modern leader compared to Tories of old”
