The weeks of Democratic hand-wringing ended suddenly on Sunday after President Joe Biden stepped out of the White House race and endorsed Vice President Kamala Harris. Her young campaign has energized Democrats. But Harris has befuddled Republicans who don’t know how to attack her, and a media that doesn’t know how to define her. On today’s episode of A Word, Jason Johnson discusses Harris’s record and her prospects with political analyst Niambi Carter, a professor at the University of Maryland’s School of Public Policy.  Guest: Niambi Carter, political analyst and author of American While Black: African Americans, Immigration, and the Limits of Citizenship.
