Why isn't Communitarianism more popular as an ideology?

[DanielX]

Because, especially in recent decades, the vast majority of Americans tend to value individual freedom over collective action; though we may differ as to the actual definition of 'freedom'.

However, many modern day Republicans, especially ones like Huckabee, are increasingly communitarian/populist. Also, the Democrats used to have a very strong populist wing (especially in the South).
