The need for electoral reform
The UK & US parliamentary systems really bug me because they're not based on PR & the results are so distorted. Trump didn't win the popular vote in 2016 - Hillary Clinton did. Johnstone didn't win the UK election in December 2019: his party gained under 50% of the overall votes cast. The SNP won well under 50% of Scottish votes in the December 2019 UK election. However, under the First Past the Post system the Conservative party & the SNP are both badly overrepresented in Westminster. Other parties are likewise badly underrepresented in the Westminster parliament under the FPTP system (in the UK parliament as a whole the LibDems & the Greens are underrepresented; Scottish MPs have far fewer Labour, Libdems or Conservatives than they should have, & there are more SNP parliamentarians than there should be). Without PR thinking voters are often forced to vote tactically, with unpredictable results. There is a similar situation in the US parliament where results are skewed by the electoral college system where states with very small populations have a disproportionate influence on the results. FPTP voting systems can result in very polarised societies because they often result in essentially 2 party politics, and other parties are squeezed out. In real life opinions are more varied, and more voices are heard.

One thing I really like about NZ is that the parliament here is elected by PR (proportional representation). Often this results in NZ having coalition governments - as it should do. Coalition governments reflect the votes cast much better than non PR voting systems, even if they make politics a less clear-cut business, & voters can cast their votes for candidates & parties they support with more confidence than in the UK. In contrast, my votes were effectively wasted votes in most of the UK elections I voted in, except for in the European or Scottish parliament elections (these have different systems of PR, the Scottish parliament having the better system, similar to NZ's).
