I genuinely think Labour won't win until they get a charismatic party leader. Politics has sadly changed now and the average knuckle dragging voter doesn't bother looking into the policies of the candidates or if they are a decent and honest person. It's all about who they like more. I mean look at Johnson. His entire political career is because people loved the floppy haired buffoon they saw on have I got news for you.
You can also look at what happened to Ed Miliband. He completely tanked because he talked nasally and looked a bit of a twat eating a bacon sandwich.
I think Starmer is a decent, if slightly boring person and I fully believe if he got elected he would do a good job to change the country for the better. But that's not gonna win enough voters over. Labour need someone oozing with charisma who will grab people's attention and really sell them on how their lives would improve under Labour while also going in hard on the tories. It's sad that's what is needed but that's the reality of politics now.
