It's not that simple. People who vote dem or rep understand the two party system is bad and has a lot of consequences. That's not at all a minority opinion.
The problem is that people are realistic enough to also realize they can't just magically, out of nowhere, break the two party system. The "vote third party!!" people are useful idiots, and we all know it.
The fall of the two party system must be thorough and deliberate. We cannot start at a presidential election, much less like two months before the election, which is always when the "vote third party!" people crawl out of the woodwork.
They don't actually give a single flying fuck about third party. Otherwise, they would vote third party locally and then on a state level so they can build up their reputation for the presidency. And, they would at least decide on which third party to support. But they're too busy fighting over each other to decide that. So they're delusional enough to think their .5% polling candidate out of 5 other .5% polling candidates can overthrow the dems and reps.
It has to be coordinated. Two party system has been build up for a very long time. We need legislation on PACs, on voting, on the electoral college, and we need the cultural shift.
You think I don't want a third party to win? Of course I do. But I'm not stupid, and I recognize that just going out and randomly voting for a third party is just a vote for the status-quo. This is part of the reason (just part, don't worry) that Trump won.
Until you, and others, can name me one specific third party and then also make your community and local representation at least 50% of the same third party, then I don't care. I don't want to hear it, nobody wants to hear it, you sound stupid, keep your mouth shut.
We have to do the work if we want results. Yeah, that means you too.
The thing that we can do is emphasize electoral reform (of the kind that enables viable third parties: runoff voting etc) as the major item in primaries. Basically no Democrat should win the primary unless this is a major item in their platform.
Note that, unlike many other reform suggestions, this one is actually viable because Congress can mandate it nation-wide, like it does today with single-member districts. All it takes is majority vote in both chambers (and yes, they should throw the filibuster in the Senate out to pass this if that's what it takes).
Without ranked choice voting or run-off elections, third party votes are worthless and essentially a vote for whoever wins. All third party voters in 2024 effectively voted for Trump, hopefully they’re happy with their choice.
The problem is those who benefit from it are also those who would have to do away with it. So they won't.
