what do labour supporters think about individual policies and how to choose a leader

i think Labour should take each and every area of policy and ask each and every member what they want - ie a lot of members accept that they are not going to agree with everything put forward by labour - ie whether for or against austerity, for or against referendum and EU etc, and find out exactly what people voting for labour actually support - re-affirm exatly what labour ideology actually is in the face of changing demographics - for how can members decide on a leader if the choice is limited to something they cannot wholeheartedly support? with Ed Miliband i felt i could wholeheartedly support what he was trying to do - i felt i understood what he was trying to do and why he adopted certain policies - we need to hear what leaders are proposing but they also need to hear the views of members and supporters - as well as of those who didn't vote labour at all
