Not sure. The SNP being relatively united is actually unusual for a political party, most contain factions and leading them is the art of preventing all out war - just look south of the border at labour or tories when it came to the EU for the last 30 yrs. I know it pisses you off when I call the snp a single issue party, but the issue (indy ref 2) at least gives all sides something to rally round and agree on.
That is very true. There seems to have been this 'bigger picture' theme for a while now just about keeping the party somewhat focused on not tearing at itself through various tensions and fallouts. Whether this one is one stretch too far, the next few weeks or months will tell.
