President Joe Biden said on Sunday he would withdraw from the 2024 presidential election race, putting the United States into uncharted territory.
Biden endorsed Vice President Kamala Harris to be the Democratic nominee this year.
Before Biden's decision was made, Reuters spoke to Elaine Kamarck, a senior fellow at the Brookings Institution think tank, a Democratic National Committee member, and author of the book "Primary Politics" about the presidential nominating process, about what could happen next.
Q: WHAT HAPPENS NOW?
A: Biden has spent the last several months accruing nearly 4,000 Democratic delegates by winning primary elections in U.S. states and territories.
Those delegates would normally vote for him to be the party's official presidential nominee at the Democratic National Convention that is set to take place Aug. 19-22, but the rules do not bind or force them to do so. Delegates can vote with their conscience, which means they could throw their vote to someone else.
By stepping aside, Biden is effectively "releasing" his delegates, potentially sparking a competition among other Democratic candidates to become the nominee.
Q: WHO COULD REPLACE BIDEN?
A: Several candidates could step into the fray.
Vice President Kamala Harris is at the top of the list, but she has had her own problems after a rocky start in the job and poor polling numbers. The U.S. Constitution dictates that the vice president becomes president if the president dies or becomes incapacitated, but it does not weigh in on an inter-party process for choosing a nominee.
California Governor Gavin Newsom, Michigan Governor Gretchen Whitmer, Kentucky Governor Andy Beshear and Illinois Governor JB Pritzker have all been floated as possible replacements. Up until now they have been Biden supporters working to help get him elected.
Q: HOW WILL A NOMINEE BE CHOSEN?
A: There could be a free-for-all of sorts between the Democratic heavyweights vying for the job.
In order to secure the nomination, a candidate would need to get a majority - that is, more votes than all the others combined.
If no one achieves that, then there would be a "brokered convention" in which the delegates act as free agents and negotiate with the party leadership.
Rules would be established and there would be roll call votes for names placed into nomination.
It could take several rounds of voting for someone to get a majority and become the nominee. The last brokered convention when Democrats failed to nominate a candidate on the first ballot was in 1952.
WHAT HAPPENS TO BIDEN'S CAMPAIGN CASH?
The Biden-Harris campaign had $91 million in the bank at the end of May, but experts on campaign finance law disagree on how readily the money could change hands.
Because Harris is also on the campaign filing documents, many experts believe the money could be transferred over to her if she is on the ticket. But there is some debate about whether Biden would need to be officially nominated first as the party's candidate before a transfer could be made.
