Got to echo this.

Unlike the low-stakes infighting nonsense that we often have, this is really important.

Multiple polls have shown that not only is Andy Burnham much more popular than Starmer (big surprise, who isn't?), but that he's more popular than Farage. And that is a big deal, because almost nobody else is.

He's an attractive choice for the left, and he's attractive for Northerners who want change - two camps which Starmer has well and truly lost.
