Is the PM - under reacting?

In contrast to the distressing pictures of the family laying flowers at their sons place of death yesterday in drab Woolwich - the prime minister with his wife and family are sunning themselves in idle luxury on the island of Ibiza. What this message says both consciously and unconsciously to the nation is - I don't give a damn about the crisis back in Blighty - I'm having fun and chillaxing! But perhaps the more important message is a statement - that he feels that he has already lost the next election. Its also a reminder of the fateful words of a former prime minister in 1979 Jim Callaghan when he was reported as saying - "crisis? What crisis", and we all know what happened next. If the European election in May 2014 go badly for the PM - then its goodnight Vienna for Cameron - at the general election in 2015. The mutinous backbenchers will sense blood and have him out. In my opinion he is already planning his retirement from politics.
