Don't expect a balloon drop quite yet. How the virtual roll call to nominate Kamala Harris will work

Delegates to the Democratic National Convention will officially select their nominee for president as early as Thursday, but unlike in past years, they won’t do so in the raucous party atmosphere of the convention floor or even during the convention itself. Instead, they’ll quietly fill out electronic ballots in the comfort of their homes, offices or vacation spots more than two weeks before the first delegate steps foot inside Chicago’s United Center. The virtual roll call will allow Vice President Kamala Harris to claim the nomination no later than Monday.
