A lot of politicians have challenged the two-party system over the years. Some examples: Ross Perot, Ralph Nader, Jesse Ventura, Gary Johnson, Andrew Yang, Tulsi Gabbard, and now Cornel West. One thing you might notice about this list is that they all have crowds of highly vocal opponents. In fact, practically everyone strongly opposes at least one of these individuals. One sort of catch-22 about the opposition to the two-party system is that the people who are unwilling to hold their noses and support a major party despite its flaws are usually also not willing to hold their noses and support an imperfect movement against the duopoly. In fact, those who are still active among the aforementioned don't cooperate with each other, either.
