Senior political reporter Aaron Blake and congressional reporter Liz Goodwin talk with “Post Reports” co-host Martine Powers about the economic policies that Harris’s campaign unveiled Friday, and whether Democrats could win a trifecta in November and make those proposals reality. They also look ahead to the Democratic National Convention in Chicago next week, where President Joe Biden will address delegates after withdrawing from the race last month. Today’s show was produced by Laura Benshoff. It was edited by Lucy Perkins and Mary Jo Murphy and mixed by Rennie Svirnovskiy. Subscribe to Aaron’s newsletter, The Campaign Moment, here. Subscribe to The Washington Post here.
