Trump’s base, in particular, feels slighted by institutions. Katherine Cramer, a University of Wisconsin-Madison political science professor and the author of “The Politics of Resentment: Rural Consciousness in Wisconsin and the Rise of Scott Walker,” sums up the prevailing attitude: “It’s this sense that, ‘Hey, wait a minute, things aren’t working out for me the way they should, and it seems like the way everything is set up is not set up for people like me.'” By taking aim at those seen as “elites,” Trump is able to create a clear target for voters angry about what they view as a rigged system.
