A few points moving forward:
Don’t blame the third parties as a “spoiler”. I’ve already told you why that’s erroneous. Even if I was wrong in this matter, the libertarian right-wing third party got the majority of siphoned off votes, not the green left-wing third party. Re-do your math and weep silently.
Also, don’t be reluctant to engage with this. This is not a movie. This is real. It has happened before – many times and many places. We will be doomed to repeat the past if the correct amount of safeguards are not enabled. That doesn’t mean we can simply label the problem, because the important words have lost their meaning a while ago. Political action needs to back up rhetoric, or all of this amounts to flatus vocis. To that extent, those on the left deluded themselves and convinced themselves that the “liberal” candidate would win because considering the alternative outcome was shielded as part of an ego defense.
We can’t afford to let that continue. If we do, we will be forced to “beat on, boats against the current, borne back ceaselessly into the past.”
