Who are the presidential candidates in 2024?

Election Day 2024 will be here before we know it, and a once-crowded presidential field is now beginning to narrow. Here is a list of candidates on both sides of the aisle, though expect to see more names drop off as the race progresses. Also included are each candidate's odds of winning from the betting site Oddschecker.

Joe Biden (D) — odds of winning: +194

President Joe Biden formally announced his re-election campaign on April 25, 2023, exactly four years to the day after he first declared his candidacy in 2019. "Freedom. Personal freedom is fundamental to who we are as Americans. There's nothing more important. Nothing more sacred," the president said at the start of a three-minute launch video. "Around the country, MAGA extremists are lining up to take down those bedrock freedoms." This is "not a time to be complacent," he continued, "and that's why I'm running for re-election." Should the president succeed in reclaiming the White House, he will be 86 at the end of his second term.

A recent poll showed him gaining momentum over Donald Trump in the crucial battleground state of Pennsylvania, but he still trails the former president in the majority of aggregates.

Donald Trump (R) — odds of winning: +104

Months before his legal fortunes took a turn for the worse, former President Donald Trump stood before an adoring crowd at his Mar-a-Lago estate and made his third consecutive run for president official. "For millions of Americans, the past two years under Joe Biden have been a time of pain, hardship, anxiety, and despair," he told the room full of Republican aides and heavyweights. "In order to make America great and glorious again, I am tonight announcing my candidacy for president of the United States."

Now, even with the 91 federal indictments against him, the former president has managed to maintain a comfortable lead over all of his opponents. He won the Iowa GOP caucuses in a landslide, capturing every county in the state except for one, and took the New Hampshire primaries. If he experiences a similar victory in South Carolina, it will likely rubber-stamp his title as the Republican nominee for president.

Nikki Haley (R) — odds of winning: +2,200

Former South Carolina governor and ex-Trump administration official Nikki Haley tossed her hat into the ring on Feb. 14, 2023, after claiming she wouldn't run in the upcoming election cycle should Trump decide to do the same. "Republicans have lost the popular vote in seven out of the last eight presidential elections. That has to change," Haley said in a roughly three-minute launch video, during which she highlighted her work as governor while echoing a familiar (and potentially loaded) refrain: "It's time for a new generation of leadership."

Some view her as the likely best candidate to beat Trump, and a recent op-ed in The Boston Globe described Haley as someone who could "rebuild the respect for Republican principles." While her campaign started off slow, Haley has steadily been gaining momentum and was described by Politico as the likely GOP candidate — if any — that will usurp the lead from Trump. She is looking for a strong showing on her home turf in February's South Carolina primary.

Ryan Binkley (R) — odds of winning: +25,000

A pastor and entrepreneur from Texas, Ryan Binkley threw his proverbial hat into the 2024 ring back in April 2023. "I believe in God, I believe in America, I believe in liberty and I believe in you. And I'm asking you today to believe in me," Binkley told supporters at the time, per The Hill. This run for president marks the CEO's first-ever foray into politics, and he's focusing on matters of immigration, national unity, and pro-life policies, among other priorities, according to his website. The company he runs focuses on “business consultancy, M&A and wealth advisory,” his website added.

Despite earning just 0.7% of the Iowa caucus vote, Binkley vowed that he was "still running and fighting for our country," the Des Moines Register reported.

Marianne Williamson (D) — odds of winning: not displayed

Love or hate her, Marianne Williamson is back. Following an unsuccessful White House attempt in 2020, which saw her drop out of the race almost a full year before Election Day, the self-help author launched a challenge against Biden roughly a month before the president had even made clear his own plans. "We all owe President Biden a debt of gratitude for defeating President Trump in 2020, but with the things that they're going to be throwing at us in 2024, we need to submit to the American people an agenda of fundamental economic reform, universal health care, ... and a guaranteed living wage," among other initiatives, Williamson said in a March 4 announcement video. Like several other candidates, Williamson's chances of winning the nomination are believed to be low, and her name is not even listed among the betting candidates on Oddschecker's presidential odds.

Robert F. Kennedy Jr. (I) — odds of winning: +2,800

An environmental lawyer as well as the son of late U.S. Attorney General Robert F. Kennedy — yes, that one — RFK Jr. is perhaps best known for his support of anti-vaccine rhetoric, beliefs that have been vehemently denounced by his own family.  After initially launching his White House bid in conjunction with the Democratic Party, Kennedy in October switched to independent, which could complicate things for both Biden and Trump alike.

The aforementioned condemnation by his own family has made him an outlier among the Democratic tentpoles. RFK Jr.'s nephew, Jack Schlossberg, said his uncle was "trading in on Camelot, celebrity conspiracy theories and conflict for personal gain," calling his candidacy "an embarrassment." However, Politico noted that RFK Jr. is also using some factors of unfavorability toward Biden to try and "seize on" an opening within the Democratic party.

Cornel West (I) — odds of winning: +99,900

Philosopher, scholar and activist Cornel West raised the perennial debate over third-party spoilers when he announced a run for president alongside the People's Party, then the Green Party, and now as an independent. "People are hungry for change," West wrote on X when announcing his switch to run as an independent. "They want good policies over partisan politics. We need to break the grip of the duopoly and give power to the people."

Like RFK Jr., though, his run as an independent means West is unlikely to travel very far in his presidential aspirations. He has recently been using the events of the Israel-Hamas war as a catalyst to draw in Muslim and Arab American voters.

Chase Oliver (L) — odds of winning: not displayed

Chase Oliver, a libertarian, announced his candidacy in April 2023, per Ballotpedia. Speaking at the Iowa State Fair, the 2022 U.S. Senate candidate out of Georgia described himself as "armed and gay," and urged a "cultural war ceasefire," per the Des Moines Register. "I don't care how you live, who you love, how you worship, how you express yourself, if you do it in peace, that's your business, not the government's," he said. Oliver is also pro-choice, supports the legalization of marijuana, and wants to see an increased focus on combating addiction and drug use in the U.S. Like Williamson, his odds of winning are so low that they are not displayed on Oddschecker.
