In a presidential primary with two black senators launching parallel attacks at a septuagenarian white man, former Vice President Joe Biden has maintained not just his front-runner status overall but his dominance with the pivotal black vote.

The affable yet gaffe-prone front-runner quickly closed in on more than 40% of the black vote shortly after officially entering the crowded primary field. One summer and weeks of racially driven attacks later, Biden’s maintained his support with black voters, with a new, post-debate Quinnipiac poll giving him a whopping 47% share of support from black voters.
