The Democratic Party is set to announce its presidential nominee by August 7, as confirmed by DNC Chairman Jaime Harrison. Vice President Kamala Harris has garnered significant delegate support for her bid, with an aim to secure a majority by Wednesday. President Joe Biden endorses Harris but can't enforce delegate votes. The DNC is committed to a fair process, utilizing virtual voting to meet Ohio's updated September 1 deadline. The goal is a unified front for the August convention in Chicago.
