If one thing has become clear since Nicola Sturgeon’s abrupt resignation, it is that the SNP has been a one-woman band. The candidates in the race to succeed her are trying hard not to be less than mediocre and failing. But one thing they know: that Sturgeon’s regime was a smoke and mirrors outfit. When not in denial, they reveal that there were shortcomings that stained her rule. There is no indication that any of them actually knows what to do with the power that they would inherit. The high-water mark of nationalism has passed. The SNP may still have almost 80,000 members: a far cry from the dizzy heights of 125,000 a few years ago. But, increasingly, members are becoming disillusioned. The way in which the leadership contest is being held is doing nothing to enlighten them, or us, about what a future SNP would actually do.
