Voters who are concerned that on the latest polls we may be heading for three years of instability have it in their hands to deliver a decisive result.
A Party Vote For ACT is worth four times a party vote for National.
This is because of a little known aspect of MMP.
Under MMP the electorates a party wins are deducted from the number of list MPs awarded.
On average it will take 60,000 votes to elect each National list MP.
Whereas it takes just 16,000 to elect an ACT MP
So the answer is easy.
Party vote ACT for three years of stability.
