YSK: No Labels is a political party trying to run a spoiler candidate for President in 2024 that should not be taken seriously.
WYSK: There funded by dark money PACS, but some good reporting has brought out these names: David Koch, Peter Thiel, Reid Hoffman, Mark Cuban, Harlan Crow, and Michael Bloomberg. Some of there members are most famous for stopping big bills. Joe Leiberman, for example, single handedly stopped the single payer portion of the ACA. Senators Joe Manchin and Kyrsen Simena kept the John Lewis voting rights act from passing, and famously kept the senate from repealing the filibuster.
Edit: please note that I made at least one mistake here (as well as some kind of boneheaded comments later). FPTP, even in the US, does not require a 50% majority, just more votes than anyone else (a "plurality"). It can still benefit parties to get to 50%, since it makes their winning more likely, and so in the absence of any drawbacks, most successful parties will still aim for it, but it isn't strictly necessary, as has been sometimes demonstrated in the UK. Thanks to squaresinger for linking a YouTube video that mentions this below. /Edit
I just want to share my thoughts on this. It started as a response to one comment, but I realized that there's a lot more that can (and I think should) be said, so here goes.
First, for those who don't know, FPTP stands for First Past The Post, meaning a system where everyone votes for a single candidate and whoever gets more than 50% (i.e. "past the post") wins the entire election (the losers get nothing). For many Americans, this might be so familiar that one would wonder how it could be any different (in a small-d democratic system), but there are in fact many alternatives: ranked voting, proportional representation, Condorcet method, etc.
They all have strengths and weaknesses, but for FPTP, and other similar systems, there's a result in political science called Duverger's law that says FPTP-like rules tend to cause a two-party system, essentially because
because even if you don't team up with a larger party you may disagree with on many issues, to get a majority, others will, and then they'll win and you'll get nothing. And since getting significantly more than 50% consumes party resources that might better be used elsewhere, but gives no reward, 50% (plus a small "safety margin") is what all the successful parties will eventually aim for, and thus you get two roughly equally-successful parties. Tiny swings in voting then lead to massive differences in outcomes, which threatens the stability and security of everyone (even America's "enemies").
So saying "just vote for third parties" (like I see some calling for here) is tone-deaf at best, or part of a cynical ploy to fracture the opponent's party at worst. Even if a "third party" does win, the best that can be hoped for under FPTP is they just end up replacing one of the two parties, becoming one of the two parties in the "new" two-party system. And the two existing parties have likely spent far more time and effort researching ways to stop even that from happening than any of us ever will.
If we, as Americans, or others with a stake in what America decides to do, want to change this (and I personally do), then we need far more fundamental changes to how the system works. Just choosing a candidate we like (whether they have any chance of winning or not) won't cut it. I don't know what's the best voting system to use, but I know I'd like to scrap the Electoral College, for a couple reasons:
Even though one might argue that Congress and the Supreme Court are more essential to reform, it's hard to deny that the President has a very large leadership role today.
One might argue that relying on a convoluted/Byzantine method for choosing the President makes it harder to manipulate, and that's probably true, but the two parties have shown that it being difficult is not a deterrent to them doing so: in fact, they likely both benefit from it by keeping smaller parties that can't afford to do it out.
It reminds me of the fallacy in computer security of "security through obscurity": if it's possible to break into the system, and large numbers of people can benefit substantially from it, then someone eventually will, no matter how hard we make it to exploit. We need to change the system, not only so that it is prohibitively difficult for anyone to exploit the system, but also to get rid of a lot of the corruption that makes most people want to exploit it in the first place.
All of this is much easier said than done, I know, but we need to explain clearly to the public why "quick fixes" won't work, before we can convince them of the need for more fundamental changes. We still need to work on figuring out the details of the best changes, but unless we can show people the reality of the deep structural problems that acually exist, why they exist, and how we know we're right about what we're saying, we'll never convince most people to change anything.
You are totally right. The problem isn't zqthat such a change from within the system can only happen from a position of immense power. So to actually fix these bugs you need to
Have enough power to change the constitution
Have gotten that power through the current system
Be so dedicated to change the system that you are willing to risk all that power for the change, because any meaningful change means that the systems that brought you to power won't work in that way anymore.
Now, to make matters more difficult, representative democraties usually spread that power over hundreds or thousands of people. So not only you need to fit the bill above, but also the top few hundred politicians in your country need to agree to potentially losing their power.
So what tends to happen is the opposite: Politicians amass power and make it harder and harder to replace them, until a war/civil war/revolution happens and the next crowd tries to make it better.
The US has had centuries to concentrate power, contrary to many European nations that were re-founded after wars in the last century.
So unless the US as we know it collapses, there won't be significant change to the better for the political system.
One of the biggest problems with making this change is that in areas where one party is dominant, voters of that party are afraid of changing the system because they fear it'll mean that they won't dominate anymore.
