You're right about maybe having some impact on people's mindsets overtime if we can get some sizable percentage voting 3rd party but voting 3rd party is still a wasted vote with respect to the current election as it won't affect the results in any way. And it's worse than wasted if you're in a swing state.
The only way to show you don't whatsoever endorse not just the republican and democratic parties but the voting system itself which I don't is to not vote.
Unfortunately, not voting because you don't support the system is indistinguishable from those who don't vote because they don't care (from the perspective of those in power) -- All the more reason to write in "none of the above" - thus not supporting any of them, but actively showing refusal of all of them. If 10% more people quit voting... I don't see how anything changes. If 10% wrote in none of the above, now you're talking major headlines
Yes, because the media isn't a cog in the machine. Lol
