As Congressional elections become more and more a national affair, why do we still have districts? Say a state gets 24 reps. Give me a ballot with all the candidates and let me mark the 24 I want. Yes the ballot will be more complicated, but this way we entirely avoid districting and the process is entirely fair (well until you consider states not being fairly drawn, but that’s one level up).

Likely it means that big cities would get all the reps and the rest of the state gets nothing.

Earlier quoted context omitted.

Why can't you just split elected representatives into two groups, regardless of stated political affiliation? One group then cuts, the other chooses.

Defections. Electeds will happily maximize their own personal power at someone else's expense. There are many examples of getting opposition support for inequity in exchange for safe seats. People outside of (partisan) politics don't often get to see that the party orgs and the politicians are usually in conflict. More so on the left than on the right.

Interestingly enough, this works even for defectors. They still have to participate in a turn-based game against a competitor.

There is a whole field of study around efficient "cake cutting" algorithms, many of which contemplate and account for defectors.

"I cut, you choose" is really the only politically viable alternative to the current state of affairs. https://slate.com/news-and-politics/2018/02/how-the-i-cut-yo...

Ah that's very clever, like when my sister and I split a candy bar in grade school. It really worked then as it would now.

How hard would it be to change the congressional election system to proportional voting by party? In California you would vote for 53 representatives, each representative would be part of a party. First the seats are divided among all parties based on some system. Then within each party the seats are given to the representatives that have the most votes within the party. This would introduce new parties to the system…

Would this require me to make 53 different votes? This sounds a like pretty complicated situation to expect educated votes for all 53 votes.

Why stop there? Why do small states get the same number of Senators as large states? All the Senators should just be from California, Texas, New York, and Florida.

Gerrymandering is a danger to democracy and it is great that researchers shine light on the different trade-offs of districting criteria. This website seems like a great demonstration of the fairness and competitiveness trade-offs.

I'd argue that every voting system that has gerrymandering as a possibly error mode is inherently dangerous. No amount of antimandering could ever be more than a temporal band-aid. There are many examples that successfully combine local representation with proportional outcome.

A better route would be proportional representation. You vote for a party-ranked list of candidates, and the top n% of the list gets into office based on the fraction of the vote the party received. Unlike single-member plurality voting, this makes third parties viable.

The small states getting the same number of senators as large states is partly a legacy of slavery. Interestingly, the constitution explicitly prohibits the 2-senators-per-state rule from being amended away (Article V).

As that is where most of the people live, why is it wrong? Why does largely unpopulated land get a vote?
