Bring back hanging
It has fuck all to do with ideology and principles and everything to do with 4000 councillors who look set to lose their seats. They'll do whatever they have to to hang onto their own little fiefdoms, and I doubt they will demand a leadership challenge on the basis of electing someone who will do exactly what Clegg is doing.
It's got a lot to with ideology as well as self-interest. The MPs still control the process - they can decide to kill off any leadership challenge if they feel that a further public deepening of internal splits will effect their careers, never mind the councillors. If they decide to stick with the current leadership there's nothing the lib-dems who want a leadership challenge can do within the party.
