JOE BIDEN PICKS KAMALA HARRIS IS BIDEN’S CHOICE TO BE HIS RUNNING MATE. Ms. Harris, 55, is the first Black woman and the first person of Indian descent to be nominated for national office by a major party, and only the fourth woman in history to be chosen for one of their presidential tickets. She brings to the race a far more vigorous campaign style than Mr. Biden’s, including a gift for capturing moments of raw political electricity on the debate stage and elsewhere, and a personal identity and family story that many find inspiring.
