It would appear that the UK is not the only country contemplating electoral reform.

Via the New Zealand Herald:  MMP vote will lead to total review of system.

The Electoral Referendum Bill – reported back from select committee yesterday – recommends a review to take place, but only if a majority vote to keep it in the referendum.

[…]

If a majority want a change, another referendum will be held in 2024 asking voters to choose between MMP and the most popular of four alternatives: First Past the Post, Preferential Voting, Single Transferable Vote or Supplementary Member (SM).

Apparently voters will be allowed to vote on whether they want to keep the MMP (mixed member proportional) system that was put into place in 1993 to replace the first past the post system that it had (i.e., like the US and UK).   Voters will also be asked which of the four above-listed alternative they would prefer.  If a majority wants to scrap MMP then a 2024 referendum will be held to determine if the most popular of the four choices in the 2024 referendum.

It is interesting that electoral reform is a major issue is both a system that has been in place for centuries (the UK) as well as a place that has had recent reform (NZ) and yet it isn’t even on the edge of the political radar in the United States to the point that most people don’t even realize that there are other voting systems that could be used.

Update:  Right after posting this I noticed that Matthew Shugart has put up a more detailed post on the subject—which makes sense since he wrote (well, co-edited) the book on this subject.
