In 2021 Joe Biden was the oldest American ever to be sworn in as president, at age 78. From day one of his presidency there was speculation he would step down for a younger Democrat rather than seek reelection. After Democrats outperformed expectations in the midterms, however, Biden supporters gained momentum. In April 2023 Biden announced he will run for reelection as president.

Robert F. Kennedy, Jr. spent most of his career working as an environmental lawyer. In recent years he has dedicated his energy to anti-vaccine campaigns. When asked about a presidential run during a visit to the NHIOP, Kennedy said, "I have passed the biggest hurdle, that my wife has greenlighted it. If things go great, we will have the funniest first lady in history, and we all need a lot of laughs, right?" (Kennedy is married to actress Cheryl Hines.)

She debated Biden and other Democratic candidates in the 2020 presidential primary but dropped out before voters cast their ballots.

In February 2023 she confirmed she will challenge Biden.

Ryan Binkley, a wealth advisor and pastor, recently crossed the 50,000-donor threshold to qualify for a primary debate (although he has yet to meet the polling requirements).

Doug Burgum surprised many politicos when he announced his presidential campaign in June. He does not have the name recognition of many other candidates, but he may get attention for recent bills he signed in North Dakota, including a ban on abortion after six weeks and a ban on gender-related care for minors. So far he is focusing his campaign on the economy and energy policy.

Chris Christie announced his campaign for president in June. He is a fiery critic of former president Trump and called him "a bitter, angry man who wants power back for himself."

Florida Governor Ron DeSantis has gained national attention for splashy, “anti-Woke” policies, from a tax break for gas stoves, to banning AP African American studies, to flying migrants to Martha’s Vineyard. Some Republicans see him as a more electable version of Trump, but others - such as Nikki Haley - argue he is "mini Trump" without any new policy ideas. DeSantis officially announced his presidential campaign in May.

Larry Elder is a long-time conservative commentator for both TV and radio. He first ran for office in the 2021 California gubernatorial recall election; he came in first among Republicans but did not get enough votes to oust Democrat Gavin Newsom. In April 2023 he announced his presidential campaign. His website states, "As a California resident, I’ve seen firsthand how decades of Democrat rule have turned the Golden State, for many, into an unaffordable dystopia. I won’t let them do the same to America."

Nikki Haley served as governor of South Carolina and U.S. ambassador to the United Nations under president Trump. While she once said she would not run against Trump, her campaign announcement in February included a clear jab at both Trump and Biden: “America is not past our prime, it’s just that our politicians are past theirs.” She also touted her success as a first-generation Indian American. “Joe and Kamala even say America is racist. Nothing could be further from the truth,” she said.

Hurd is a former U.S. representative and CIA officer. He is known for his bipartisanship in Congress and is unafraid of criticizing former president Trump.

Former Arkansas governor Asa Hutchinson, a vocal critic of Donald Trump from a deep-red state, announced his presidential campaign in early April.

After a decade working in finance, Steve Laffey served as mayor of Cranston, Rhode Island from 2003 to 2007. While his residence is in Colorado, he told WMUR, "I'm here for three months. I'm living in Manchester. My kids are coming. My family will come. You thought the Kennedys campaigned hard in the '60s? Every single person in New Hampshire will meet my family. And we're going to breakthrough right here, right in New England, where I'm from."

There was a rift between former vice president Mike Pence and former president Donald Trump over the certification of the 2020 election results and the attack on the Capitol January 6th. Since then Pence published a book and has been traveling the United States to publicize his policy ideas. One notable difference between Pence and some other Republicans is his vocal support for pro-life policies.

Vivek Ramaswamy is an entrepreneur who gained attention from Republicans after publishing “Woke, Inc.: Inside Corporate America’s Social Justice Scam.” In an editorial announcing his campaign he wrote, “I am launching not only a political campaign but a cultural movement to create a new American Dream—one that is not only about money but about the unapologetic pursuit of excellence.” Ramaswamy is new to politics and may face an uphill battle on name recognition.

Sen. Tim Scott is competing against a fellow Carolinian, former governor Nikki Haley. He said in a recent Iowa speech, “I see a future where common sense has rebuilt common ground, where we’ve created real unity, not by compromising away our conservatism, but by winning converts to our conservatism.”

Shortly after the 2022 midterm election former president Donald Trump announced his third presidential campaign from Florida.
