“Iowa is a template of what white people will do,” said Brown, whose group played a key role in rallying black voters to the polls in Democrats’ upset win in the 2017 Alabama Senate race. “And I hate to acknowledge it, but it influences how black people see a candidate, too.”

“So if [Warren] wins Iowa or New Hampshire, it’s a ball game changer,” said Brown.

Warren’s support among black women, according to Morning Consult, has inched up from 8 percent three months ago to 13 percent in a survey released this week. Biden currently has 42 percent support among black voters, the poll showed. Morning Consult is one of the few polls that provides breakdowns of their findings by gender and race.
