They won't elect a moderate leader, they'll double down then wonder why they are out of politics for the next 10 years.
Truth is online forums like el'reg are generally left leaning, but the UK as a whole is very centrist. Win that, you win power. Blair showed that, Boris for all his bumbling knew that, Corbyn and momentum still don't get it. The majority sit in the centre, you can lean a little one way or the other but if you lean too far to the left or right, you are ******.
and before anyone says it - no Boris isn't far right, he's right but he's no extremist (other than an extreme buffoon at times).
