Party affiliation is already a problem, List systems make that worse.

Years ago two of my friends lived in Vauxhall in London. That spy building in central London where James Bond works? That's in Vauxhall (and it is really for spies, though real intelligence agents do not look like James Bond), they lived like 10 minutes walk from there.

Vauxhall is pretty far left even for a city borough, but they ended up with Kate Hoey as their Labour MP. Kate - despite being a representative of a left party was nevertheless pro gun rights, pro fox hunting, and pretty luke warm on LGBT issues, she was also, which led to her finally be thrown out by her local party, pro-Brexit.

But the people of Vauxhall weren't really voting for Kate Hoey the woman who likes fox hunting and isn't too bothered if they make abortion illegal again, and who is supporting Brexit even though they don't want it - they were voting for Labour, a centre left party and Kate had Labour's endorsement.

Maybe under PR Kate ends up finding a home in some party that more closely tracks her personal beliefs, but, equally maybe not. And so people end up voting for something they don't really want.

I think that given simply counting is apparently too untrustworthy in our post-truth world, we might as well do something more sophisticated like Instant Run-off or Approval, but I don't approve of Proportional as a goal.
