According to Edison Research, Trump won whites making less than $50,000 by 20 points, whites making $50,000 to $99,999 by 28 points, and whites making $100,000 or more by 14 points.
Trump won white women (+9) and white men (+31). He won white people with college degrees (+3) and white people without them (+37). He won whites ages 18–29 (+4), 30–44 (+17), 45–64 (+28), and 65 and older (+19). Trump won whites in midwestern Illinois (+11), whites in mid-Atlantic New Jersey (+12), and whites in the Sun Belt’s New Mexico (+5). In no state that Edison polled did Trump’s white support dip below 40 percent.
Part of Trump’s dominance among whites resulted from his running as a Republican, the party that has long cultivated white voters. Trump’s share of the white vote was similar to Mitt Romney’s in 2012. But unlike Romney, Trump secured this support by running against his party’s leadership, against accepted campaign orthodoxy, and against all notions of decency. By his sixth month in office, embroiled in scandal after scandal, a Pew Research Center poll found Trump’s approval rating underwater with every single demographic group. Every demographic group, that is, except one: people who identified as white.
