To me, the most telling words in this Guardian piece are these;
Even Labour supporters do not trust their party: only 36% of current Labour supporters, and just 26% of its 2005 voters, think the government is telling the truth about debt.
If they think the Labour Party is lying to them about something so fundamental, why do they still support it? Where is their anger at being (as they think) deceived? Do voters no longer even hope for honesty in politics or government?
