basically you have a donut effect. the rurals and inner cities got more red but the suburbs more blue. the total can be overall higher for the gop statewide (big scores in new york or new jersey in 2024) but its terrible for local races since dems still win the inner cities and now win more of the suburban congressional seats. as to the why that happened its mostly about the nature of the political coalitions and how they realigned on immigration and cultural issues. turns out a lot of minorities dont like woke dei stuff or mass migration of illegals.
