Back when we were kids we had a phrase called being a front runner. It was derogatory in the sense that these people had little to no loyalty. If say the Yankees were in first place, they loved them. If the Yankees sucked, we’ll they hated them. It was different than respecting another team when they weee successful. Normal, stable people would respect the other teams, but they still had their team they always loved no matter how they did. I don’t even watch baseball or sports that much, but this is a clear example and applies to politics as well.
A lot of these people changing opinions about Trump or becoming Republicucks, are seeing him as a better path forward for their own / their cultures political gain than the Democrats. Once they get theirs and ‘make it’ they will simply just continue to help their own because they are tribal. Indians and Asians and on a personal level I get along with them great are the perfect replacement class. They are hardworking, intelligent, polite, and take orders well because of their culture. But again very tribal, they will put their own first and most have little loyalty to the country. They aren’t as aggressive as Muslims in pushing their religious ideology though, and are more peaceful in nature. There’s no populism or nationalism here, just another way for the Republican donor class to make more money. Of course the Trump worshipers will never admit that.
