Harris passes delegate threshold for nomination: AP survey

• Just over 24 hours after Harris officially launched her presidential campaign, more than 2,200 delegates from over 30 states had endorsed the vice president as the Democratic nominee.

The big picture: President Biden gathered the support of nearly 4,000 delegates in his near-sweep of the primary race — but his Sunday announcement just weeks before the Democratic National Convention has left those delegates untethered to a candidate.

• Biden endorsed Harris just after announcing his departure from the campaign trail, with his second-in-command saying her "intention is to earn and win" the Democratic presidential nomination in response.

Driving the news: Under party rules, Harris is required to win the support from 1,976 delegates on the first ballot of voting to earn the nomination.

• AP emphasized that while its survey could demonstrate the early edge Harris appears to have gathered among convention delegates, it is still an "unofficial tally."

What's next: The party's convention is set to begin Aug. 19 in Chicago, but the DNC confirmed on Monday that it will hold a "virtual roll call" to select its party's presidential nominee before Aug. 7.

• The new timeline makes it difficult for any candidate other than Harris, who has earned the support from virtually every major Democratic lawmaker, to secure the party's nomination.
• The Democratic body's rules committee reportedly plans to hold a meeting to discuss nomination framework Wednesday at 2pm ET Wednesday, which is expected to be broadcast live.
