Philadelphia, where Biden is basing his campaign headquarters and is holding his kickoff rally, is particularly important to Democrats if they are to make up for the failings of Clinton’s 2016 campaign.

African American turnout in Philadelphia fell. Biden hopes his ties with the black community will allow him to change that in 2020.
