If Kamala Harris wins the nomination, who could be her running mate?

A Democratic party ticket led by Kamala Harris seems increasingly likely as scores of high-profile elected Democrats line up to endorse her for president in the wake of Joe Biden’s withdrawal from the race.

In Biden’s announcement that he would no longer pursue a second term, he thanked Harris “for being an extraordinary partner in all this work”, and later, in endorsing her, called his choice to run with her in 2020 “the best decision I’ve made”.

In short order, a series of powerful endorsements rolled in, including from Democrats formerly viewed as possible presidential candidates themselves, some of whom are now being floated as potential vice-presidential candidates on a Harris ticket.

If Harris takes up the mantle for the Democratic party, one of her first major decisions as a candidate will be choosing a running mate. Harris has not indicated who she would consider, but here are some of the names Democrats are floating, so far, as possible vice-presidential candidates.

Andy Beshear

Beshear’s unlikely position as the Democratic governor of Kentucky – a state that voted for Trump by a margin of 25 points in 2020 – makes him a compelling vice-presidential candidate for the Democratic ticket. In office, Beshear has vetoed Republican bills banning abortions and gender-affirming care for transgender minors, although the GOP-controlled state legislature was able to override his vetoes in both cases.

Beshear would also offer a contrast to Trump’s running mate, JD Vance, the Ohio senator who in his popular 2016 memoir Hillbilly Elegy claimed Appalachian culture was to blame for the region’s impoverishment. On MSNBC’s Morning Joe show Monday, Beshear endorsed Harris and knocked Vance. “JD Vance ain’t from here,” Beshear said, nodding to Vance’s depictions of Kentuckians as lazy.

Mark Kelly

Arizona senator Mark Kelly would offer swing-state credibility and could be a favored choice among party elites, given his role as a moderate in the Democratic party. His record as a combat veteran and former astronaut could also be a draw for independent voters. Kelly has been an advocate for gun reform after a shooting left his wife – former US representative Gabby Giffords – partly paralyzed.

“I couldn’t be more confident that Vice-President Kamala Harris is the right person to defeat Donald Trump and lead our country into the future,” Kelly wrote on X on Sunday.

Josh Shapiro

Shapiro, the governor of Pennsylvania, has been a strong supporter of Biden and a faithful surrogate for his campaign. Shapiro has a track record of winning races in the swing state, serving as Pennsylvania’s attorney general for six years before he was elected governor in 2022. An outspoken opponent of Trump for years, Shapiro has nonetheless built bipartisan support within Pennsylvania; a May Philadelphia Inquirer/New York Times/Siena College poll showed he enjoyed 42% approval from Republicans in the state – a rare showing of support in an age of hyper-partisanship.

Shapiro endorsed Harris Sunday, saying she had “served the country honorably” and describing her as a unifying figure.

Roy Cooper

The 67-year-old governor of North Carolina touts a long record in the state as a representative, attorney general and governor. Cooper is approaching the end of his time in the office (North Carolina governors are term-limited), where he has fought for the passage of bipartisan legislation despite the Republican party controlling the state legislature. In 2023, Cooper signed into law Medicaid expansion, which some red states have declined despite the measure being guaranteed under the Affordable Care Act.

Cooper also quickly endorsed Harris’s presidential campaign. “I appreciate people talking about me, but I think the focus right now needs to be on her this week,” he said on MSNBC’s Morning Joe show on Monday.

Wes Moore

Maryland governor Wes Moore has also been floated by some Democrats as a running mate alongside Harris. Moore, who is the only sitting Black governor in the US, is widely considered to be a rising star in the Democratic party. Sworn into office in January 2023, Moore’s record in office is short. He has said that he would not want to be tapped as a vice presidential candidate, saying: “I want to stay as the Governor of Maryland, I love the momentum we are seeing right now in the state of Maryland.”

Gretchen Whitmer

Michigan governor Gretchen Whitmer, a Democratic star who some hoped would run for president this year, has been floated as a potential running mate, even if it’s highly unlikely that Harris would pick another woman. Whitmer endorsed Harris Monday morning – but quickly dispelled the notion that she would be joining Harris on the ticket. “I’m not leaving Michigan,” Whitmer said at a media event. “I’m proud to be the governor of Michigan.”

Whitmer, who enjoys broad popularity within the Democratic party for helping to flip the swing state blue, emphatically backed Biden before he dropped out of the race.

Pete Buttigieg

US transportation secretary and former mayor of South Bend, Indiana, Buttigieg rocketed into political stardom during his 2020 presidential bid, which gained surprising momentum given his sparse political record. Buttigieg, who is a navy veteran, has spoken powerfully about coming out in 2015 and later marrying his husband, Chasten Glezman Buttigieg. Buttigieg has served during a tumultuous time for US transportation systems – from the devastating and high-profile derailment of a train in East Palestine, Ohio, to airline meltdowns, to the Key Bridge collapse in Baltimore.
