Sour grapes about rotten apples?

Calton is longing for some sunshine, if only to put an end to all the sour grapes we have been having lately. This time it is an ex-Scottish Tory, Malcolm Macaskill, who, in an interview with the Sunday Herald, blasted the Tory machine as "rotten to the core" and said that the Scottish party was an "inept and morally corrupt" organisation. (This after he received a substantial out of court settlement from them, which the party describes as a 'goodwill gesture'.) It doesn't seem to Calton that there is very much goodwill towards the Tories on Macaskill's side but, rather, the feeling that he was dumped to make way for one Ruth Davidson who now happens to be the party leader. The Scottish Conservatives disagree, citing his failure to disclose business failures as the reason he was bumped off the list. Who is right? Who knows. More importantly, who cares?
