There’s no reason this wouldn’t continue indefinitely.
Wait, what? Why would it continue indefinitely? Lets say we had a Green Party with polling showing 90% of the population interested in that party. In what reason would you not vote for the Green Party (Assuming they are aligned with your goals)? Even if the polls are off we still have an extremely good chance of winning.
vote thresholds are necessary to be recognized as a major party and receive things like federal campaign funding and a spot in televised debates.
You don't technically need money to win an election, it helps, but all that matters is the votes. If you don't debate a popular candidate, your opponent can call you a coward. No one wants to debate anyone, it's just better optics to engage.
If your position is that you should support a third party up until it comes time to vote, then where is that support?
Ohhh, maybe you got me, I haven't been paying much attention to the 3rd party polling. Any progressive 3rd party candidates coming close to Biden or Trump? If they are, then you win, and let me know.
Also, let me just say, if it is not too late, that I support all candidates that agree with me. Have any candidates in particular you want me to verify?
