What makes Trump-MAGA popular with Hillbillies

“If you can convince the lowest white man he's better than the best colored man, he won't notice you're picking his pocket. Hell, give him somebody to look down on, and he'll empty his pockets for you.”
― Lyndon B. Johnson

MAGAs are motivated by perceived loss of social status. Their anger stems from loss of power and status as women, gays, Latinos, blacks and Asians make progress. Their talk of Latinos and African Americans all being criminals, etc. is just an excuse to inflict cruelty on them. It's all about the cruelty and power.
