This is all true, but there’s more:

• Our election campaigns are six weeks by definition. No political ads filling the airwaves the rest of the time.
• We have preferential voting. You don’t have to choose only between the shit and shit-lite parties. You can vote for someone else, and still put shit-lite as your preferred option if the independent you voted first for didn’t get in.
• The electoral commission will help pay for your campaigning if you secured 5% of the vote. Evens the field a bit for not-rich people to run.
• Political signs on houses are pretty rare. Maybe a couple of diehard fans.
• Nobody gets real angry at you if you vote for someone different.
