The Spectator Coffee House blog very rarely features posts from a pro-Labour perspective. If it has ever before featured a post from a hard left perspective, I certainly can't remember it. The author of today's piece, Robert McGregor, doesn't seem to have written for the site before.
So is it entirely a coincidence that this once in a blue moon post just happens to take a "bad news for Sturgeon" angle? Probably not. I suspect even Fidel Castro would be welcome at the Spectator as long as he wanted to bang on about the latest "blow for the SNP".
Turning to the substance of the post, is it actually true that Sturgeon will be beside herself with worry about a Corbyn win? I think it's probably fair to say that the SNP would have preferred a boring win for boring Burnham, because it would have changed absolutely nothing, and more of the same suits the SNP just fine. Corbyn introduces unpredictability into the equation - his leftiness might undermine the SNP's pitch, but equally he might preside over such disunity that next year's Holyrood election will be even less of a contest than we currently expect. We just don't have a clue how it will play out, and uncertainty is scary. One thing we can be sure of, though, is that the 'Red Tory' jibe is about to give way to 'utter shambles', which is potentially just as potent.
And if the state of play is going to change, it certainly hasn't happened yet. Corbyn may be packing out medium-sized halls in Scotland, but he's had no impact on recent local council by-elections, all of which have been won by the SNP on mammoth swings.
