This video is totally worth watching.
It's not a bad video, but makes an error where it says "third party voters hurt themselves"
As things stand, third party voters know quite well that their candidate will not "win"
If someone votes third party, it's usually because the two major parties have drifted so far into insanity that they can't in good conscience vote for them, but still feel a civic obligation to vote. True believers are rare.
I do agree that proportional representation is needed, particularly in the House. But, well, good luck with that. Queen Lion doesn't control the electoral rules, Leopard and Gorilla do - and aren't about to make any changes.
