I wouldn’t say anything has replaced it yet, more that the Trump admin is trying to do so currently by removing a lot of programs, banning words, purging employees, etc. Whether that will be successful remains to be seen but coastal liberal culture is very dominant and I don’t see it being replaced any time soon. And I guess you could call the other culture conservative culture.
I would argue MAGA is somewhat revolutionary from the neoliberal globalist two party consensus in the last 30-40 years. Coastal liberal culture and its components might see itself as revolutionary, woke and so on, but I see it as just a continuation of liberal culture. After all, wokism, or whatever the term is, very comfortably fits in elite coastal liberal culture and that culture has been dominant for decades.
