If Biden chooses to resign AFTER the convention, then the DNC gets to have a meeting and basically choose who they want to give all these delegates to as their new front runner. They made these new rules back in 2022 because this was always the plan. They realized they couldn’t rig it with the super delegates anymore after they pissed off their own base with Bernie so this was their new solution to still installing who they want.
Q: WHAT HAPPENS IF BIDEN STEPS DOWN AFTER THE CONVENTION?
A: If Biden steps down after the August convention, the 435 members of the Democratic National Committee would choose a new candidate. The members would meet in a special session to select a nominee.
Q: WHO ARE THESE 435 DNC MEMBERS?
A: They are divided equally between men and women as well as various constituency groups including labor leaders, LGBTQ representatives, and racial minorities. Of the total, 75 are appointed at-large by the chair, while the rest are elected in their respective states.
Q: WHO COULD NOMINATE AN ALTERNATIVE IN THAT CASE?
A: To nominate a candidate to replace Biden on the ballot, that person would have to have the support of a minimum number of DNC members -- perhaps around 60, though the exact number would be determined by the DNC's rules committee, which would lay out the rules for the proceedings before they started.

Under Article 2 of The Bylaws of the Democratic Party, the Democratic National Committee (DNC) has the responsibility to fill vacancies in presidential and vice presidential nominations between national conventions.
In the event of a vacancy on the national ticket, the chairperson would call a special meeting. Under Article 2 § 8(d), questions before the DNC, with some exceptions otherwise outlined in the charter and bylaws, are determined by a majority vote of the DNC members who are present and voting by proxy. The bylaws also state that voting to fill a vacancy on the national ticket must proceed in accordance with procedural rules adopted by the Rules and Bylaws Committee and approved by the DNC.

COVID-19 concern or strategic for last minute change?
Change of Batter coming?
WHY WAS SHE 'saved' from officially announcing?
WHY WAS SHE 'reserved' for a last minute change?
How do you attempt to 'sneak one in'?
