The results make clear that American politics is polarized not on the basis of class or even ideology, but on identity. The United States is currently split into two camps:
One side open to mass immigration and changes to the country’s traditional racial hierarchy, the other is deeply hostile to it.
Trump and congressional Republicans did their best to exploit these divides — remember the caravan? — and the best political science we have suggests that such divides exist between Americans who live in different places and socialize with different people.
This is a longstanding divide in America, one that accelerated under President Barack Obama.
