As Joe Biden steps aside, who will replace him?

The Democratic Party is now looking for a new candidate to run for president after Joe Biden announced he would stand down.

He has endorsed Kamala Harris – but Barack Obama says the Democrats should create a process that identifies an “outstanding nominee”.

Here is a look at who might replace him as the candidate to take on Donald Trump.

Vice president Kamala Harris

Vice president Kamala Harris has the backing of Joe Biden who called her “an extraordinary partner”.

In a post on X he wrote: “Today I want to offer my full support and endorsement for Kamala to be the nominee of our party this year.

“Democrats – it’s time to come together and beat Trump. Let’s do this.”

Earlier, the Biden campaign had been “quietly assessing the viability of vice president Kamala Harris’s candidacy against Donald Trump in a new head-to-head poll”, Sky News’ partner network NBC News reported.

Harris, 59, is the first woman to serve as vice president, the culmination (so far) of a career of firsts and breakthroughs.

She was born in Oakland to immigrant parents, her father came from Jamaica to become a distinguished economist at Stanford University and her mother was a cancer researcher who emigrated from India.

Regarded as a pragmatic path-breaker, Harris rose from local prosecutor to California’s state attorney general and then to US senator, before being picked as Biden’s running mate in 2020.

She has high name recognition and the highest polling among Democrats who could seriously be considered a candidate, sources within the Biden campaign told the Reuters news agency.

She would also take over money raised by the Biden campaign and inherit campaign infrastructure, which would be helpful should she seek to run for president.

However, her personal approval ratings could prove a stumbling block. One recent poll gave Harris a 29% favourability rating, with 49% rating her unfavourably, and 22% saying they had no opinion or hadn’t heard of her.

Gavin Newsom

California governor Gavin Newsom, 56, is an established figure in the Democratic Party and among the names being floated as a potential successor – now or later.

However, he has now endorsed Kamala Harris as the presidential candidate, calling her “tough”, “fearless” and “tenacious”.

“With our democracy at stake and our future on the line, no one is better to prosecute the case against Donald Trump’s dark vision and guide our country in a healthier direction than America’s vice president, @KamalaHarris,” he said on X.

He has a background in business, encompassing restaurants and hotels, in his career before politics.

Newsom first came to national attention when, while the mayor of San Francisco, he and other city officials started handing out same-sex marriage licences – in direct violation of state law at the time.

His stock continued to rise and in 2019, he rode a landslide victory to his state’s top job, becoming governor of California.

He is seen as a strong voice within the party and a talented debater, but his critics point to a poor record across a number of key issues in his state.

This includes high homelessness, drug problems, immigration issues, law and safety, high taxes, and more.

Gretchen Whitmer

Gretchen Whitmer’s swift ascent over the past two decades – from law school graduate to Michigan’s governor – has established her as a prominent figure within the Democratic Party.

Her status was solidified in 2022 with a decisive re-election and her party’s success in flipping both chambers of the state legislature, granting Democrats full control for the first time in nearly four decades.

Whitmer, 52, has been pushing the topic of abortion access in her role as co-chair of the Biden campaign, saying he is on the “right side” of the abortion fight despite his lacklustre performance in the recent debate on the question of reproductive rights.

She blames Trump for fuelling the political hatred that motivated a plot to kidnap and kill her that was foiled by the FBI in 2020.

When asked if she would consider becoming a candidate this year if Biden were to step down, she responded with a definitive, “No”.

Josh Shapiro

“Get shit done” is Josh Shapiro’s slogan for how he wants to run Pennsylvania.

The governor is a rising star in the Democratic Party and is seen as one of a handful of governors who have been building their national profiles and positioning themselves for a 2028 run for the White House – before the issues with Biden emerged.

However, the 50-year-old son of a physician and former state lawmaker, county commissioner, and state attorney general, has now backed the vice president after Joe Biden stepped aside.

“I will do everything I can to help elect @KamalaHarris as the 47th President of the United States,” he said in a post on X.

“The best path forward for the Democratic Party is to quickly unite behind Vice President Harris and refocus on winning the presidency.”

Michelle Obama

Well-known and popular from her time as first lady when her husband Barack Obama was president, there are many on the Democrat side who would love to see Michelle Obama as the party’s nominee.

Indeed, Trump supporters have fixated on the notion of Michelle Obama’s swooping in to replace Biden in an attempt to diminish the president’s political viability and stoke the GOP base.

An Ipsos poll found she is the only hypothetical candidate to definitively defeat Trump head-to-head, and she also topped the charts in favourability among registered voters.

But would she be interested?

Earlier this year, her office told NBC News she was not planning to run for office in 2024.

One of her aides pointed to her discussion last year with Oprah Winfrey to reflect her thinking – and why she would most likely never appear on a ballot herself.

“Politics is hard,” she said in the Netflix special. “And the people who get into it… you’ve got to want it. It’s got to be in your soul, because it is so important. It is not in my soul.”
