Scotland's cause needs the SNP. That's just cold, hard realpolitik denied only by self-indulgent fantasists. But if we need the SNP we need the SNP to be fit for our purpose. That it presently isn't is all to apparent. In part because of its reluctance to make the commitment required of it ahead of the 2021 Scottish Party election. Partly on account of the party's internal troubles. While the former is a matter for the Yes movement as a whole, the latter is entirely a matter for SNP members.
For more than three hundred years Scotland has been poisoned by a toxic political union.
