The party of the people no longer has a government. Today Mr Hollande dissolved it because some ministers were critical of his policies. Typical really, unless you agree you will be removed.
Politicians can be quite ruthless when it comes to staying in office. I see the leadership of the SNP as exactly the same, no different, and where all this new people power is to come from is bizarre as it is not seen anywhere else in the world that I can think of. Maybe you have been influenced by repeats of Citizen Smith.
You appear to be comparing the leadership of French party that has been in office for a tad over two years and has now failed, to the leadership of a Scottish party that has been in office for a tad over seven years, four as a minority government and the last three with an overwhelming majority, and has served the country rather well in face of some of the most crippling of austerity measures. The main focus of the government in that time has been the people of the country, and they have served them well - far better than other parties have done/would have done. So your unfavourable comparison is not really warranted IMO.
