BC's referendum

Last month British Columbians voted in favour of the single transferable vote by a margin of 57 percent -- 3 percentage points short of the 60 percent required to implement this reform to the province's electoral system. However, Russ Kuykendall asks two sensible questions:

If STV is so great, why was there not a plurality of options for reform of B.C.'s electoral system? Why was there one, and only one, option put before British Columbians?

Admittedly, it is somewhat ironic that, although proportional representation is an electoral system well suited to a democracy with more than two partisan groupings, BC's voters were asked to approve only one form of PR as the alternative to the current first-past-the-post system. Might it have been better if several alternative forms were put before voters to be ranked on a preferential ballot? Perhaps.
