Americans are near universally convinced that third-parties are a dead end, which becomes a self-fulfilling prophesy. I’ve never understood it and I would’ve thought having two obviously non-viable candidates would challenge that assumption, but it doesn’t seem like anything will. The classic Simpsons bit where both candidates get replaced by evil space aliens but still get elected because “what are you going to do, vote third party?” was not an exaggeration in the slightest. Americans just accept anything.
