As for Labour's pre-emptive block on minimum pricing, which has left them no room for manoeuvre, it's depressingly predictable but hard to put it down to anything more sophisticated than spite mingled with stupidity. They act as if they're in the local council instead of MSP's in the Scottish Parliament.
The inane verbal contortions of unionist observers who disagree with Labour's stance but must try and support it anyway are equally predictable. How nice to see the old unionist tactic of blaming all sides for Labour's failings getting its monthly outing. (Nicely dealt with by mrbfaethedee)
