After this post:
Why stick to the concept of seats anyway? How about this: You give your vote to a representative, then all folks who were voted for a sufficient number of times (to exclude crackpots) form an assembly where the voting power of each representative is determined by how many votes they got. Votes are transferrable: If 900 people voted for me but I don't feel like becoming a representative, I can pass on those 900 votes to someone else. (It might be wise to restrict this practice to a degree to prevent a couple issues I can't think of right now.)
Putting it in a more thought-out way:
- Votes become transferrable objects.
- Everyone starts out with one vote.
- Everyone can at any time take their own vote away from the person that currently has it.
- You need X amount of votes to be admitted to Parliament and get to debate and actually vote on laws there, where X is sufficiently high to keep the number of representatives reasonably low.
- To pass a law representatives having a total of Y votes between them need to consent to it, where Y probably needs to be chosen quite a bit below 50% to accomodate votes in possession of people not currently in Parliament. In particular this includes non-voters.
Why I think this might be a good system:
- This method of voting is both proportional and personal.
- Election cycles are no longer a thing, since votes can be changed at any time.
- The effort of being politically active is lowered tremendously: If there's a party you like, you can just give your vote to them and then never have to bother with active participation again unless you decide that you no longer like that party.
- Political groundwork is rewarded: Representatives have a strong incentive to be active in their target group even outside electoral cycles.
- Politics is no longer tied to geographical areas: Suddenly it becomes viable to be a representative specifically of, for example, the gay community. This gives marginal groups a much better voice in Parliament.
- No more landslides because of singular events! Political events will have more of an impact on the distribution of power outside of election season and less during compared to the current system.
- Power shifts in general will become much more gradual. This should be considered a good thing, since continuity is desirable in incredibly many areas.
To counteract possible negative effects it may be wise to couple this system with strict term limits on government positions. A possible downside may be the splintering of Parliament into too many bickering factions, leading to frequent government changes ŕ la Italy back in the day, but I believe this can be overcome with the right political culture - and, as seen with Italy, is a danger that is also present in the more conventional incarnations of proportional representation.
