"broad cultural movement" would be something like the nsdap or communist revolution. and saying trump would make deep changes is just very naive.  both republicans and democrats are controlled by the same financial oligarchy and they both have the same foreign policy just as they both believe in the same fundamental ideology which is america's founding ideology. they just disagree on implementation. for example the maga movement wants to ensure america's economic hegemony by going to trade wars now, whereas the democrats correctly realize that the world economy favors the usa and want to keep that status quo. the republicans want to go to war over israel, the democrats want to war over ukraine but they both have the same goal.  they are both bad for us regardless of if blue team or red team is in charge. they both want to keep us subjugated. trump wants to rip up our trade agreement (even though he literally designed it, lol) and prevent us companies from investing in mx, he has also talked about invading us. kamala is less aggressive but would just keep the status quo which keeps us nicely desindustrializad and open to rape by us multinationals.
