Why Hamilton West matters

Electorate seats decide who sits in Parliament, but the party vote decides how many seats each party gets. An electorate can still change the result: it can bring in a party that's under 5%, or add overhang seats that raise the number needed to govern. The seat forecast shows how often that happens.
