> The overwhelming majority of Americans are happy to fit themselves into one of two political parties.
I don't know about overwhelming. Typical voter turnout for US presidential elections over the last few decades has been right around 50% (it ticked up notably in 2020). Many people who do not vote report disillusionment with both major parties as a significant reason for their choice.
I've heard similar. Of course, it's hard to know whether they'd also report disillusionment with ten (or whatever) political parties.
And, really, the idea of political parties is itself not wholly compatible with individualism.
But, the broader point is that the current state of affairs seems antithetical to the notion that individualism is a major feature of American society.
American "individualism" reminds me of all the people who call themselves "free thinkers", but managed to free think their way to exactly the same set of beliefs.
