To some degree yes, but mainstream US is still far more culturally uniform from state to state than Europe's countries are. In Europe most of countries are nation-based and as such encapsulate also all the possible differences in ethnicities, languages, culture, religion and history to a much higher degree. Imagine each race/denomination/ethical group in US having their own independent state with their own laws and ways of life, and you get something like Europe.
