Kamala Harris campaign has plan to secure majority of Dem delegates by Wednesday: report

Officials with her presidential campaign and allies have been making hundreds of phone calls since Biden stepped out of the race and endorsed Harris on Sunday to gather support ahead of the Democratic National Convention, which is set to begin in Chicago on August 19. Locking in delegates would block challengers and ensure that Harris replaces Biden on the ticket against Trump in November.

Harris needs the support of around 1,969 out of the 3,936 Democratic delegates at the convention to receive the nomination, with around one-quarter pledging to back her so far.

Democratic National Committee Finance Chair Chris Korge, a Florida delegate, told the outlet, "Biden's endorsement of her has been very powerful in getting donors to give money and in delegates ... to ultimately pledge for her. With him endorsing the vice president, I think by the end of business on Wednesday she'll probably have enough pledged delegates to go over 50 percent."

Sources told Reuters that Tennessee became the first state on Sunday to pledge its 70 delegates to Harris. Two top campaign officials said that Wednesday was the day they’re aiming for securing support, and another source with knowledge of the matter told Reuters, "Yes, working toward that" when asked about the Wednesday timeframe.

While most Democratic delegates had been committed to Biden following primaries in states this year, they are not bound by rules or laws to back anyone following Biden dropping out.
