What if neither side represents your interests? What "election" is there in that case?

There's more than two sides here. None of the 14 parties with >1 seat in parliament fully represents my best understanding of how to improve the country and world on any time scale (long or short), but quite a few of them come reasonably close and I would vote for them without much hesitation

(Heck, I wish there were fewer parties, like if five single-topic good parties (bij1 against racism, pirate party for internet freedoms, volt for international collaboration, party animals for environmental welfare, etc., plus greenworkersparty as the current overarching big boy) would band together, it'd be a much easier choice!)

That not every country is so lucky (not all of them have free elections, or elections at all) is a shame indeed, but at least for countries like mine I'd be much happier to have a government arrange a system than a tech corporation and foreign laws. Presuming that the 2-party system you speak of is the USA's, at least both corps are governed by your own laws, that's something!

Simply live somewhere that doesn’t have a broken electoral system.

Can you candidate yourself in that election?
