In that case, there's no reason not to switch to some more fairly representative system, for which there are various possibilities but PR systems are the best known (https://en.wikipedia.org/wiki/Proportional_representation).
I spent a number of years in Italy, and several come to mind that I saw there:
* Representatives are beholden to the party, not to some local area.
* Smaller parties can play 'kingmaker'.
It has some real advantages (it's nice being able to vote for someone that actually agrees with you AND not have your vote be wasted), but my experience in New Zealand is that:
1. It enhances the power of parties and thus increases partisanship
2. It allows small parties to play kingmaker. In the NZ case, the perennial kingmaker party is corrupt and virulently nativist.
If, hypothetically, you were concerned about the partisanship, corruption, and nativist policies of current American politics, PR may not be the panacea you hope. I think it was quite unlikely for the American system to yield Trump as president (we just got very unlucky) but it would be quite likely for a PR system to yield Trump as a kingmaker with a vastly outsize influence on the policy of the resultant government. That's not obviously better, on balance.
Actually I'd be interested in seeing some kind of delegative democracy system like Liquid Feedback. It has some features in common with PR (mostly the emphasis on having to negotiate a coalition given the voting results), but I'm hoping it wouldn't share the problems you outlined?
Hmm, now you mention it, didn't something like that happen to the Weimar Republic?
There was kingmaking of a more personal kind going on behind the scenes, but not of the minor-party-exercises outsized influence kind.
Enhancing the power of parties is a function of systems that establish proportionality by party list (either wholly or by MMP) more than it is directly of proportionality (proportionality vs. a duopoly-reinforcing system encourages party cohesion, because it reduces the cost of people splitting off to form their own party because they dissent from existing parties, but that decreases rather than increasing the power of parties, in that the party majority or leadership -- outside of party list systems -- has less that they can threaten wayward members with to keep them in line.)

Similarly, for the second, the US has two very strong political parties and this would really only change House of Representatives (one portion of one branch of the federal government) so the kingmaking power would be extremely limited as the vast majority of the Senate & Presidency would still end up with the stronger parties.
The second is just making visible a problem that exists even in the US system with intraparty factions.
The gerrymandering problem isn't created by individual districts, it's created by first past the post voting.
Suppose you replace this with range voting or approval voting. Now it doesn't matter where you draw the district lines, because there can be twelve viable candidates and no matter where you draw the lines, each district will choose the candidate who best represents the district. A candidate can run, and win, on a platform which is specific to that individual district without having to align with an existing party's platform because winning is no longer contingent on the backing of a major party.
Which means you can't draw the lines to favor your own party because all it will do is cause some new party/candidate to appear that better represents whatever arbitrary district you created than you do.
And then you get to keep all the advantages of individual districts and avoid all the disadvantages of PR.
Yes it is.
> it's created by first past the post voting.
FPTP creates other problems, but not the gerrymandering problem. OTOH, systems that support parties may mitigate some effects of gerrymandering.
> Now it doesn't matter where you draw the district lines, because there can be twelve viable candidates and no matter where you draw the lines, each district will choose the candidate who best represents the district.
The problem with gerrymandering is that single member districts let you choose what kind of candidates will be elected by how you draw draw district lines, and by doing so you can assure that some interests are over or underrepresented in the legislature compared to their prevalence on the population. You've not stated a way in which range or approval voting change that (and you won't find one, because they don't.)
Sure they do. If you concentrate all the people who care about a particular issue into one district, and you make candidates not affiliated with a major party viable, then that district can elect a representative who cares about that issue a lot and will be willing to trade issues the district cares less about in order to get it, without having to worry what the party leadership wants.
And how is PR supposed to solve this problem? It only replaces districts with parties, and then you're stuck choosing from a small handful of parties whose members all stick to the party line and you're forced to choose one that doesn't represent you on some subset of issues.
The only better way to solve that problem is direct democracy, which would bring in a whole different set of problems.
Imagine you have 100 single-winner districts that are each roughly 50/50 Dem/GOP, with the slight edge breaking 50/50, so that your legislature has 50 reps from each party.
Now we redistrict to pack a bunch of Dems from the GOP-majority districts into one super-Dem district, shaving down their margins in numerous districts. We could conceivable get 99 GOP reps even though the population is 50/50 Dem/GOP. That super-Dem district "discards" or "wastes" 50% of the votes of the Dems inside it, because they're surplus votes in excess of what they need to win the district.
Now imagine you switch to 20 5-winner districts elected with PR. The Dems could win all five seats with conceivably 83.3% of the vote (5 candidates getting 16.6% each means they get all the votes). So the most you can possibly wast is 16.7% of the votes instead of 50%.
> It only replaces districts with parties
No. Most PR systems still have districts. Exceptions like Israel, where the whole country is one big district, tend to be the poster children of PR gone wrong. Plus there are PR systems where you vote for candidates, not parties. Single Transferable Vote in Australia's Senate is an example. You just rank the candidates (although many voters blindly follow the guidance of their preferred party).
Another cure to Gerrymandering is algorithmic redistricting, which I'm supportive of. https://www.youtube.com/watch?v=kUS9uvYyn3A
As for Score Voting (aka Range Voting) there is a proportional form of it. http://ScoreVoting.net/RRV.html
However I agree that even the single-winner form would reduce the negative impact of Gerrymandering (also, getting Score Voting is a much more consequential/impactful change than eliminating Gerrymandering). The reason it mitigates Gerrymandering is that it tends to reduce polarization and two-party dynamics, electing broadly appealing centrist winners. If you try the "packing" strategy with Score Voting, you tend to "move the ideological center", so a district that's already going Democrat doesn't become a /dev/null for surplus Dem votes that you want to effectively burn. If you pile on more Democrats, you can just keep pushing the center more Democratic. This is a theoretical argument mind you, but I think a reasonable one.

Imagine you have 100 single-winner districts with range voting so that there aren't two parties, or any strong parties at all.
Then the platform needed to win a district is district-specific, because a candidate with a district-specific platform beats any party's general platform in that district. Even if the winning candidate is a member of a party, the candidate still has to do what the district wants over what the party wants or they'll lose the seat.
The winning candidate in single-district range voting is literally the one that gets the highest average rating within the district, so it optimizes for no surplus at all.
If there was any then an independent candidate could show up with a platform that captures it by aligning more closely with the district and thereby win the seat.
The only way to do better than that is to do the same thing but with smaller districts, at the cost of having more members of the legislature (and in the limit it becomes direct democracy).
> No. Most PR systems still have districts.
I don't mean there are no districts, I mean that in PR instead of being stuck with a district that might not represent you in some ways, you're stuck with a party that might not represent you in some ways.
And PR STV doesn't fix that. Anything that increases the number of constituents per representative inherently can't, because that is what causes the problem to begin with. Diluting each vote by 20 times but giving each constituent 20 times as many representatives doesn't cancel out.
If a state upstream from your district is dumping poison in the river, no candidate could win that district without addressing it. But with any kind of PR, it's possible for every representative to ignore it because the affected voters split between twenty representatives, none of which need 1/20th of their votes enough to address the problem.
And RRV looks like it would create a lot of strange incentives, like giving a lower score to candidates you strongly like if you think they're likely to win regardless, except that if everyone thinks that way then that candidate loses.
