How to Replace a Presidential Candidate?
(excerpt)
If the Democratic Party were to replace Biden after the convention, it gets more complicated. Practically speaking, it is nearly impossible to call a second convention, so the decision to replace Biden would fall to about 447 DNC members, down from the nearly 2,000 delegates needed to clinch any candidate the presidential nomination. Here is what the Democratic Party’s rules and bylaws state about how this post-convention process would work:
“In the event of death, resignation or disability of a nominee of the Party for President or Vice President after the adjournment of the National Convention, the National Chairperson of the Democratic National Committee shall confer with the Democratic leadership of the United States Congress and the Democratic Governors Association and shall report to the Democratic National Committee, which is authorized to fill the vacancy or vacancies.”
Rep. Nancy Pelosi, D-Calif., Sen. Chuck Schumer, D-N.Y., DNC Chair Tom Perez, and chair of the Democratic Governors Association Gov. Phil Murphy, D-N.J., would issue the report to the DNC, and the new nominee would be selected through that process.
