The conditions that prevailed in 2011 are no more. The 2014 referendum and the ongoing constitutional war of attrition have fundamentally changed the dynamics of how we do politics, of how we think politics. Unionist support is continuing to rally behind the Conservatives, and this, along with the continued success of the SNP in the constituency vote, will now always work against the SNP. Yet, Stewart McDonald is right. The SNP strategy in 2011 has been the only one that has worked, and it has won an SNP majority. It can win that majority again – theoretically, at least.
