Electoral reform was a bad promise made to fix a non-existent problem.  Failure here is a happy event, not an outcome to be mourned.  (To be clear, I think PR is an awful system, so personally very happy with failure of electoral reform).  Since people learn the most, and often only from, failure, here's to hoping the PM takes the correct lessons from this failure: 1) don't make foolish promises; 2) If it ain't broke, don't fix it; 3) Pursue things you actually mean to complete and have a real chance to complete.
