What do the SNP have to do to stay in office?

At their conference in Glasgow this weekend the Scottish National Party faithful are doing their best to keep their spirits up. Everything to play for.  Polls ambiguous. Alex will see us right.  No one thinks Iain Gray is a leader.  Perhaps not.  But the SNP is up against one of the greatest challenges in modern political history.  How to break the link between Labour and the soul of Scotland.  The Scottish Labour Part my be bereft of ideas, lost for leaders, out of touch and fearful of office.  But almost inspite of themselves, Labour still look like being the favourites to win the Scottish election in May.  The bond of sentiment is just too strong with the Scottish voters.  When the Tories are in office in Westminster, Scotland just votes Labour.
