The promise to change the electoral process before the next election was politically expedient - and stupid.

The issue of electoral reform is important - but the Liberals did not have a mandate to implement changes to the system before the next election.

This does not mean they should stop doing analysis.

What they should do -- is research options, provide cost / benefit analysis; and launch an education campaign.

Then during the next election there should be a 2 part referendum question on the ballot:
 (a)  do you support changing the system from first past the post (current method)

 and 
(b) which option would you prefer?

In order for the referendum to pass -- there must be a majority (and perhaps a super-majority) in favour of changing the system.
If the answer to the first question is yes -- the largest % of the votes for option (b) would determine the electoral system to change to.

Other questions (such as changes to voting age) would be up to future governments
