HOW THE DEMOGRAPHIC SHIFT could hurt Democrats, too. “It’s assumed that, as the United States becomes increasingly non-white, white Democrats will continue to support the party. But a substantial amount of social-science evidence suggests a different conclusion: As the United States becomes more racially and ethnically diverse, liberal whites might start leaning Republican.” If that happens, it will be because of the surprisingly common anti-white racism emanating from so many Democratic operatives and pundits. Given that whites are still a very substantial majority, such a shift would be devastating for the Democrats. If they can’t carry 30-40% of whites, they can’t win.
