Donald Trump: The former president maintains a strong, but early, lead in polls despite his multiple, escalating legal woes that he’s turned into a key talking point for his campaign—casting them as “political witch hunts,” a messaging strategy that appears to be resonating with voters.

Ron DeSantis: DeSantis reportedly plans to launch a presidential bid next week, fresh off a Florida legislative session where he’s championed a string of right-wing policies that could lay the groundwork for his campaign platform.

Asa Hutchinson: Hutchinson, who served eight years as governor of Arkansas until the end of last year, launched his campaign on April 26—Hutchinson has been a vocal critic of Trump, going as far to say the January 6 Capitol riot “disqualifies” him from running again and that he should drop out of the race after being indicted in New York.

Chris Sununu: The New Hampshire governor, who took steps toward a potential run in February with the launch of a new super PAC, told CBS on May 4 he would make a decision “in the next month or so,” while also dragging Trump for his reported plans to skip the early GOP primary debates: “you cannot stand in front of America and say, ‘I’m a fighter, but I’m going to wimp out and not get on a debate stage,’” he said.

Tim Scott: The South Carolina senator—who raised speculation that he would enter the race earlier this year when he embarked on a multi-state tour to promote his political message—launched an exploratory committee in mid-April, paired with a video announcement where he vows to “never back down in defense of the conservative values that make America exceptional.”

Mike Pence: The former vice president, while traversing the country to promote his new memoir, So Help Me God, has left open the possibility of a presidential run, and also has the backing of a new super PAC, “Committed to America,” run by former aides to Trump critics, Georgia Gov. Brian Kemp and former Maryland Gov. Larry Hogan, CBS reported.

Doug Burgum: The North Dakota governor is expected to make a decision whether to run for president sometime within the next few weeks, sources told CBS and CNN on May 18, and did not rule out a candidacy in a recent interview, telling North Dakota newspaper The Forum, “there’s definitely a yearning for some alternatives right now,” referring to Republicans’ concerns about Trump’s and DeSantis’ electability.

Chris Christie: Though he has yet to formally announce his candidacy, the ex-Trump ally turned critic, who is weighing a second run for the GOP nomination after dropping out of the 2016 primary race, has cast himself as the only candidate who has the courage to take on Trump and has chided DeSantis for his war with Disney.

Nikki Haley: After vowing not to run against Trump, the former South Carolina governor became his first official challenger in February, calling for a “new generation of leadership” in a video announcement, while attacking President Joe Biden’s “abysmal record” and noting that Republicans have lost the popular vote in seven out of the last eight elections, but Haley is polling at a low 4% among potential 2024 GOP presidential candidates, according to FiveThirtyEight.

Vivek Ramaswamy: Less than a week after Haley announced her campaign, the 37-year-old investment firm manager—who made Forbes’ list of America’s richest entrepreneurs under 40 in 2016 with a net worth of $600 million at the time—entered the fray with a video announcement in which he dubs “covidism, climatism and gender ideology” as “new secular religions,” a statement that builds on what he calls an “anti-woke” message detailed in his 2021 book, “Woke, Inc.”

Mike Pompeo: Also out with a new book titled Never Give an Inch: Fighting for the America I Love, the former secretary of state told CBS in January he would decide on a 2024 presidential bid in “the next handful of months.”

Larry Elder: The former 2021 California gubernatorial candidate and conservative radio talk show host announced his long-shot candidacy in a Fox News interview on April 20, where he told ex-host Tucker Carlson, “America is in decline.”
