Biden replacement talk stirs Democratic strategy

President Joe Biden's halting debate performance has led some in his own party to begin questioning whether he should be replaced on the ballot before November.

There is no evidence Biden is willing to end his campaign.

And it would be nearly impossible for Democrats to replace him unless he chooses to step aside.

Here's why:

Delegates Biden won in the primaries are obligated to support him

Every state has already held its presidential primary. Democratic rules mandate that the delegates Biden won remain obligated to support him at the party's upcoming national convention unless he tells them he's leaving the race.

Biden indicated that he had no plans to do that, telling supporters in Atlanta shortly after he left the debate stage, "Let's keep going." Biden campaign spokesperson Lauren Hitt was even clearer, saying Friday: "Of course, he's not dropping out."

The political parties control the conventions and their rules. The Democratic National Committee could convene before the convention opens on August 19 and change how things will work, but that isn't likely as long as Biden wants to continue seeking reelection.

The current rules read: "Delegates elected to the national convention pledged to a presidential candidate shall in all good conscience reflect the sentiments of those who elected them."

VP Kamala Harris couldn't automatically replace Biden

The vice president is Biden's running mate, but that doesn't mean she can swap in for him at the top of the ticket by default. Biden also can't decide whether she should replace him should he decide to leave the race.

The Democratic National Convention is being held in Chicago, but the party has announced that it will hold a virtual roll call to formally nominate Biden before in-person proceedings begin.

The exact date for the roll call has not yet been set. If Biden opts to abandon his reelection campaign, Harris would likely join other top Democratic candidates looking to replace him.

But that would probably create a scenario where she and others end up lobbying individual state delegations at the convention for their support.

That hasn't happened for Democrats since 1960, when John F. Kennedy and Lyndon B. Johnson jockeyed for votes during that year's Democratic convention in Los Angeles.

Other potential Democratic candidates would also face challenges

In addition to the vice president, others who had endorsed Biden in 2024 while harbouring their own presidential aspirations for future cycles include California Governor Gavin Newsom, Michigan Governor Gretchen Whitmer, Pennsylvania Governor Josh Shapiro, Illinois Governor J. B. Pritzker and California Representative Ro Khanna.

Still others who Biden bested during the party's 2020 presidential primary could also try again, including Senators Bernie Sanders of Vermont, Elizabeth Warren of Massachusetts and Amy Klobuchar of Minnesota, as well as Transportation Secretary Pete Buttigieg.

If Biden were to abruptly leave the race, conservative groups have suggested they would file lawsuits around the country, potentially questioning the legality of the Democratic candidate's name on the ballot.

But Elaine Kamarck, a senior fellow in governance studies at the Brookings Institution in Washington, who wrote a book about the presidential nominating process and is also a member of the Democratic National Committee's rulemaking arm, said that courts have consistently stayed out of political primaries as long as parties running them weren't doing anything that would contradict other constitutional rights, such as voter suppression based on race.

"This is very clear constitutionally that this is in the party's purview," Kamarck said in an interview before the debate. "The business of nominating someone to represent a political party is the business of the political party."
