She received zero electoral votes from her 1.07% of the popular vote in 2016. In fact, she did not win a single county or district nationwide in 2016. It appears further that no third party candidate has received any electoral votes since 1968. How do plan on breaking that streak this year? Polling says you won’t. I understand that the possibility exists that out of nowhere a giant surge of third party voters could show up and do it. But reality up to now shows they probably won’t since they previously haven’t.

You’re right that neither the Democratic nor the Republican party will give up their privilege. And the past 50+ years of results says you won’t take it from them by voting 3rd party in the general. You will have to change the parties from within by getting those new candidates to run in Dem/Rep primaries instead and then showing up to vote them onto the ballot. It will take multiple election cycles.
