What have you heard from Labour (Scottish or UK) on the strike - they cannot even bring themselves to say they support it?
Salmond needs to steer a very clever route, certain sections of the media (The Scotsman, Telegraph, Evening Stanfdard, The Times) all despise the independence agenda and are doing their damndest to instil baseless fear. Why should he gift them easy targets.
Whether the other parties supported it or not they had an opinion.
If Salmond needs to steer a clever route then maybe talking about something other than independence could be a clever strategy. There are other UK issues that are worth his time, surely?
