What happened to people voting for the Green party and supporting the concept of moving away from a two party system?
Yes... the GOP is still winning the popular vote by quite a large margin in a fat lot of good that will do you sort of way. But the real eye opener should be that only 1.81% of Americans supported a third Party candidate. There was a time when Ralph nader won 10% of the Presidential vote in one state as a Green Party candidate. In 2000, Ralph Nader won almost three percent of the vote and the Green Party hit the 5% needed to be considered an actual first tier major party in multiple states.
Heck in Minnesota we elected a third Party Governor and almost elected a third Party Senator. Both were from what used to be a rather viable "Independence Party".
Now in recent years, the Democratic machine has spend millions in legal expense to keep the Green Party off the ballots in most every swing state. Ever since Nader received nearly 100,000 votes in the 2000 Florida Presidential election, the left has insisted that the Green Party was a spoiler Party. You will notice in Georgia (for instance) that the only other candidate getting votes was the Libertarian. There was no Green party allowed. In fact only 26 states allowed Green Party candidates on the ballot.
So what is also interesting is that certain states have adopted a ranked voting system with the idea being that more people would vote third Party and possible help ween us off a two party system. But what has basically happened is that ranked voting has opened up the idea of running multiple candidates from the two major parties, which basically just makes things confusing (see Alaska).
At the end of the day, we are decreasing the amount of third Party candidates rather than increasing them. When was the last time you saw one on a debate stage? We are increasingly becoming tribalistic and almost cultish in our support of one major Party or the other. There is literally no rhyme or reason for it other than obvious gaslighting, cognitive dissonance, and bias confirmation.
