While much has been made of Biden’s late surge, we should note that that’s not true for all groups. Among black voters, aggregate preliminary exit poll data shows that both early deciders and late deciders went overwhelmingly for Biden, with no difference between them. And it’s also interesting that late-deciding Hispanic voters didn’t support Biden at quite the same rate as late-deciding white voters, even though his share about early deciding Hispanic and white voters was the same.
Whenever they decided, black voters picked Biden
