Harris, 55, does not fit the stereotype of Trump’s suburban housewife. She’s Black and Asian American, the daughter of immigrants from Jamaica and India. She’s also a U.S. senator from California and a former prosecutor and state attorney general.

Between the lines: There’s a racial undertone here.

The suburbs were two-thirds white as of the 2010 Census, down from 81% the decade before, and since then the suburbs have continued to diversify.

By 2010, Frey said, the 100 largest metropolitan areas in the U.S. counted more Black residents in the suburbs than the cities. For Latinos, that shift happened even earlier.
