What if the unions didn’t decide?

Someone asked me what would the result of the Labour leadership election if the unions bosses didn’t have 20% of the vote. This is pretty easy to calculate as you weight the caucus and the members 50% each. If the union bosses (barely 100 bosses vote in five of the six unions) did not get 20%, the results would have been:

1. Round 1 – Robertson 41.0%, Parker 22.2%, Little 20.7%, Mahuta 16.2%
2. Round 2 – Robertson 42.4%, Little 34.2%, Parker 23.4%
3. Round 3 – Robertson 55.7%, Little 44.3%

So without the unions Little would have been third on first preferences and easily lost to Robertson in the third round.
