When both candidates are too evil to vote for then this is the rational choice. Your vote is counted and so people see it when they look. Many minor parties have gotten everything they want without ever winning - when the vote margin between you and an opponent is just a few percent, attracting those who care enough too vote for a third party makes a loss into a win.
Sure other voting systems give more power to other votes, but you still get power.
If you consider Biden too evil to vote for, I don't know what to tell you, He's been one of the best presidents we've had recently and the resurgence of unions we're experiencing is thanks to him.
You can tell the terrible ones because they have an R next to their name. Clinton, Obama, and Biden have all been at the very least inoffensive and reasonable.
Well, I guess if that's been going on for decades at least it's a vote that can be safely discounted. Also no, it won't make a difference. At least not in the US. The math of it is demonstrably that it won't make a difference, especialy if you do it repeatedly. As the guy above said, you change the system so that it makes a difference first (which you may or may not get to via voting) and THEN it'll make a difference. Until then it's just performative absenteeism. Unless you are not in the US and instead live in a parlamentarian proportional system, in which case carry on.
It will only make a difference when third party candidates run for something other than president, where that party can establish a track record of getting something done in local and regional venues. Only coming out every 4 years does nothing to sway non-3rd party voters, particularly when it’s people like Jill Stein who very clearly demonstrate their sense of ethics isn’t any better and they’re just as likely to act in their own financial self-interests, and essentially dupe their voters into donations that get misappropriated. She’s even had at least one judge say as much in a ruling against her after the last election. We’ve been explaining this for many elections now, but you just don’t listen. Until then, 3rd party votes just amount to spoilers.
Great, win more, in more places, for more significant periods of time, and actually show accomplishments, then we can talk about it being a better alternative.
