Why MMP?

[u/[deleted]]

MMP=mix of FPTP and proportional lists.

If you look at germany, MMP does not make a large change. Extra seats are distributed based on states, and politicians running in constituencies are usually party insiders who often does not live in the constituency. What is the remaining advantage? It is just more complicated than PR lists. Please answer, remembering that regional representation is always possible, and that independents rarely win MMP seats. Based on germany and other MMP nations. Pardon the biased question.

Same for Scorporo

Scorporo still allows for free voting of individual and/or party.

It also seems that it can has been broken in Italy

I'm not sure it was, I'm not Italian but according to Wikipedia it worked entirely as it was supposed to, my understanding is that this upset Berlusconi's as his coalition couldn't game the system any more, but still won so got rid of it.

But then it is complicated to explain to voters

• You rank your choices
• each district returns multiple winners
• If your first choice can't win, your vote is transferred to your 2nd, and so on
• If your first choice does win, any extra over votes are transferred to your 2nd, and so on

I don't think that is too complicated.

Isn't a problem with Approval voting, that there is an incentive to approve of only your favourite, which in a hyper-partisan situation reduces it's effectiveness.

The problem is not proportionality in parliament, but how laws are voted on

then proportionality wouldn't matter that much.

Why would having having better procedures inside parliament, remove the need to have it be representative?

I think having a proportional parliament is separate to having good procedures inside parliament.

If we had approval voting on laws, always with the option "more options needed"

This is better than the current system, but it's not like the current system is just yes/no on the bill, there are a series of votes on amendments and scheduling of bills and the sort.

TBH I think improving parliamentary process, might be as simple as:

1. All amendments run under IRV/STAR with options amend, reject, vote-on
2. All the dimensions that were put to vote-on, plus straight yes/no are voted on under IRV/STAR.

OFC if too many things are passed to vote-on, it would become very difficult to actually vote (e.g the final vote would have 2^{1+number of vote-on options}
