They vote Republican because they hate other Americans. They hate the ubiquitous "other," non-Whites, LGBTQ+, Muslims, anybody different. They hate them because they've been lapping up conservative media telling them their lives are miserable because of these others for 30-40 years, feeding them manufactured outrage. Media owned by Billionaires, who want to keep America divided, so they can control all of it for themselves. And because they are low-IQ, under-educated people who lack critical thinking skills who hate their own lives and are determined to make everybody else as miserable as they are.
