Pro tip: You better get used to two-party systems, you're living in one!
Seriously, 3rd parties a total dead end in America and most, like our stupid AC here, who push them are doing so to sow distrust in one party (usually Democrats) to favor the other (Republicans) or just generally sow distrust in the system in general, usually form foreign actors (cough). Like every 4 years the Russians activate Jill Stein out of her hibernation pod.
Until America changes *how* we vote away from First-Past-The-Post then voting 3rd party is a fools errand, it only serves to assuage the vain egos of politically incoherent people. In a FPTP system a vote for a 3rd party is basically support for whoever the winner ends up being. Same for staying home instead of voting. That "Uncommitted Movement" only served to help Trump.
We have a process to hear and vote on a hugely varied group of candidates, they're called primaries and maybe if more than 30% of people voted in them we'd get candidates we like better.
Moving to Ranked Choice, Approval Voting, STAR voting, these are all much better systems of how to vote but until we get those 3rd parties are dead ends. The Libertarians are cooked, completely subsumed by MAGA and fascist chuds like LPNH and the Green Party is just a Russian Op at this point. The LP had the chance to shoot their shot in 2016 to get that 5% and they failed, completely. It's joever.
The winner in 2024 was doing to be the D or R. In 2028 it will be the D or R. Get used to it, stamping your feet and pouting won't change that. 2028 will be one of the rare times we will have 2 primaries, probably a field of 20+ people, plenty of varied choices, there's your chance.
