One of MMP’s benefits is an increase in proportionality and a decrease in wasted votes.
The Electoral Commission’s proposal to get rid of the overhang by reducing the number of list seats by the number of electorate seats which exceed a party’s would do the opposite.
It would reduce proportionality and increase the number of wasted votes by discounting some party votes.
If, as happened in last year’s election, there was a one seat overhang there would be one fewer list MP.
But there could be a lot more than one electorate seat out of proportion to its list vote because this provision would encourage gaming.
Parties could get candidates to stand as independents in electorates and not stand a candidate themselves in exchange for the independent’s support in parliament and potentially government.
This could result in several independent MPs and a corresponding reduction in list MPs.
If people don’t like the way candidates who win seats can bring in other MPs on their coat tails, they’d like the potential to game the system in this manner even less.
I can’t follow the Commission’s logic for this proposal
It would get rid of the coat-tail provision and replace it with something far more unfair and open to abuse which also reduces proportionality.
