Who's running to be U.S. president in 2024?

Former U.S. vice-president Mike Pence became the latest Republican to officially jump into the 2024 U.S. presidential race on June 5, joining Donald Trump and others in the growing list of Republicans and a few Democrats seeking to unseat President Joe Biden.

Here is a list of the declared 2024 hopefuls from both parties.

Trump announced his election campaign last November, even as he faced criticism from within his party over his support of candidates who performed badly in the 2022 midterms. He has been the front-runner ever since, with a firm grip on his base. The 76-year-old former president even increased his standing in polls after he was indicted in connection with an alleged hush-money payment to a porn star. At the same time, he remains unpopular with much of the U.S. electorate. 

Florida Gov. Ron DeSantis launched his presidential campaign bid in a highly anticipated live audio chat with Elon Musk on Twitter. But the event was plagued by technical problems, prompting mockery from his rivals and casting doubt about his viability as a candidate with enough support to defeat Trump, his one-time ally. His campaign said he raised $1 million within an hour of his presidential announcement, and $8.2 million in the 24 hours after his campaign launch.

The former U.S. vice-president declared himself a candidate in the 2024 Republican race for the White House on June 5, setting up a fight against his former running mate, Donald Trump, whom he once loyally stood by but refused to back when Trump tried to overturn the results of the 2020 election. A staunch social conservative, Pence has warned against the growing populist tide in the party, and advisers see him as the only traditional, Reagan-style conservative in the race.

A former governor of South Carolina and Trump's ambassador to the United Nations, Haley, 51, has emphasized her relative youth compared with Biden and Trump, as well as her background as the daughter of two Indian immigrants. She has gained a reputation in the Republican Party as a solid conservative who has pitched herself as a stalwart defender of American interests abroad.

The only Black Republican U.S. senator declared his candidacy on May 22. Scott, 57, has low name recognition outside his home state of South Carolina, but his optimism and focus on unifying his divided party have helped him draw a contrast with the more aggressive approach by some of his opponents. Scott supporters, however, acknowledge that while his sunny demeanour is a selling point, it may not be enough to defeat the front-runners.

The former Arkansas governor launched his bid for the White House in April with a call for Trump to step aside to deal with his indictment. Hutchinson, 72, has touted his experience leading the deeply conservative state as proof he can deliver on policies Republican voters care about, citing his record with tax cuts and job creation initiatives as particular sources of pride. Still, his name recognition remains limited outside Arkansas.

The conservative talk radio host ran unsuccessfully in California's recall election against Gov. Gavin Newsom. Elder, 71, announced his candidacy on Tucker Carlson's now-cancelled show on Fox News, and tweeted, "America is in decline, but this decline is not inevitable. We can enter a new American Golden Age, but we must choose a leader who can bring us there."

A former biotechnology investor and executive, Ramaswamy, 37, launched a firm in 2022 to pressure companies to abandon environmental, social and corporate governance initiatives. He announced in February he was running for the Republican nomination. The political outsider remains a long-shot candidate.

U.S. President Joe Biden announced he would run again on April 25, four years to the day after he declared his 2020 candidacy. The 80-year-old Democrat, already the oldest U.S. president ever, confirmed his intentions in a video in which he declared it his job to defend American democracy.

The best-selling author and self-help guru launched her second, long-shot bid for the White House on March 23. She ran as a Democrat in the 2020 presidential primary but dropped out of the race before any votes had been cast. 

An anti-vaccine activist, Kennedy, 69, is also making a long-shot bid for the Democratic nomination. He is the son of the late senator Robert F. Kennedy, who was assassinated in 1968 during his own presidential bid. Kennedy has been banned from YouTube and Instagram for spreading misinformation about vaccines and the COVID-19 pandemic.
