An appearance by Pete Buttigieg on Friday morning on New Hampshire talk radio is fueling ongoing speculation that the U.S. Secretary of Transportation in President Biden's administration may be mulling another White House run in 2028.

Buttigieg, a 2020 Democratic presidential candidate who is considered a potential contender for the next nomination race, has made numerous radio appearances across the country during his four years steering the Department of Transportation, including a bunch in New Hampshire, which prides itself on being the first-in-the-nation presidential primary state.

But with President-elect Trump a month away from returning to the White House, and Democrats scrambling in the wake of November's election setbacks to find a path out of the political wilderness, Buttigieg's latest radio appearance in New Hampshire is grabbing increased attention as the extremely early preseason moves in the party's 2028 presidential primary race will soon start.

And the guest segment by Buttigieg on the statewide morning news-talk radio program "New Hampshire Today" is bound to spark more 2028 speculation.

"The only thing I'm sure is next is a little vacation," Buttigieg said when asked by host Chris Ryan about his plans once his tenure as transportation secretary sunsets on Jan. 20.

Buttigieg said he and his spouse, Chasten, "are ready to spend a little time together. I'm ready to be around our three-year-old twins a little more, and I'm determined not to make any life decisions too quickly in the new year."

"But I will find ways to make myself useful, and maybe that's running for office, and maybe that's not. I'll take the next few weeks and months to work through that," Buttigieg shared.

And he emphasized that "I know what I care about. I care about how communities, like the place where I grew up, find a better future. I care about how to make sure technology makes us all better off and not worse off. I care about how the infrastructure issues and opportunities I've worked on can develop. I care about public service. I care about our democracy, and I will find ways to work on that, whatever shape that might take."

Buttigieg, a former naval intelligence officer who deployed to the war in Afghanistan and who served eight years as mayor of South Bend, Indiana, was a longshot when he launched his 2020 presidential campaign. 

But his campaign caught fire, and he narrowly edged Sen. Bernie Sanders of Vermont to win the Iowa caucuses before coming in close second to Sanders in the New Hampshire presidential primary. But Buttigieg, along with the rest of the Democratic field, dropped out of the race and endorsed Biden as the former vice president won the South Carolina primary in a landslide, swept the Super Tuesday contests and eventually clinched the nomination before winning the White House.

During his tenure as Secretary of Transportation, Buttigieg has made a handful of official visits to New Hampshire, most recently earlier this year. And two years ago, in a political trip, he headlined the New Hampshire Democratic Party's major autumn fundraising gala.

Asked in the interview whether he'll be returning to the Granite State in the near future, he quipped, "I'm sure I'll turn up before too long."

Buttigieg, in recent years, has also made regular appearances on the Fox News Channel to highlight the Biden administration's efforts. This year, he served as a high-profile surrogate on Fox News and elsewhere across the media landscape for Biden, and later for Vice President Kamala Harris, on the campaign trail.

After his 2020 presidential campaign, Buttiegieg moved from red-state Indiana to neighboring Michigan, which is a key battleground, and now calls Traverse City, Michigan, home.

In recent weeks, Buttigieg has fielded calls by some Michigan Democrats urging him to consider a 2026 run for governor, to succeed Democratic Gov. Gretchen Whitmer, who is term-limited.

"I haven’t made any decisions about, big decisions about my future," Buttigieg told reporters earlier this month in Detroit, in a line that he would repeat in this week's New Hampshire radio interview.

As Democrats hope to retain the governor’s seat in the swing state of Michigan with Gov. Gretchen Whitmer term-limited, a top Democratic figure has launched an independent bid, leading to a search on the left for an alternative standard-bearer.

Three-term Detroit Mayor Mike Duggan, viewed for some time as very likely to seek the governor’s office, reportedly surprised the state’s body politic by announcing he will do so as an independent.

"I went to Lansing and built relationships with Democrats and Republicans. We took our neighborhoods out of the darkness of burned-out streetlights and we lit the entire city to the national standard… and reduced Detroit's unemployment rate to its lowest rate in more than 30 years," Duggan said in his campaign launch video.

"The current system forces people to choose sides that find solutions. I want to see if I can change that."

He struck a similar tone in recent remarks to reporters:

Duggan said in his final year as mayor he wants to "establish a working relationship with the Trump administration," and noted he had done so with fellow Motor City native HUD Secretary Ben Carson one term prior.

He also told The Associated Press he views many Americans as being "tired of both parties and tired of the system – and so I want to offer people a choice."

That choice led Democrats to reportedly pivot to a prominent Indiana native who recently moved north to his husband’s home state.

At an event with Detroit autoworkers, one man shouted a question about the Lions – rather than Transportation Secretary Pete Buttigieg’s home-state Colts – which the AP illustrated as a potential challenge for the Traverse City newcomer to connect with Michiganders if he decides to run.

Another man at the event praised Buttigieg’s willingness to be "one of the few" politicians to speak to both liberal and conservative media audiences.

Buttigieg has said he won’t make any official political decisions on "how to make myself useful" until after his current boss, President Biden, leaves office, but has been contacted by several Michigan Democrats about entering the race.

Duggan’s announcement, however, was met with derision from Michigan Secretary of State Jocelyn Benson, another potential Democratic contender.

"In moments like this, we don't flee from the party, but we stay and fix it," Benson told FOX-2, which reported she is considering tossing her hat in the ring.

Andrew Feldman, a Democratic strategist in the Great Lakes State, told the AP that people are "shocked and angry" at Duggan for eschewing the Democratic Party label.

"Many view this as a serious situation where Mike Duggan could put the governor’s mansion in the hands of Republicans and roll back years of progress," he said.

While the left wing is divided between Duggan’s independent run and jockeying to fill the Democratic row on the ballot, the Republican race appears wide open.

"You know what, [20]26 is always in the back of my mind, but right now, we’re focused on [20]24," conservative media host Tudor Dixon – the 2022 Republican nominee – said just before the presidential election when asked about running again.

Other names floated in the Michigan press include businessman Perry Johnson – who briefly ran for president on the GOP line in 2024 – businessman Kevin Rinke, and several sitting GOP lawmakers.

Adding to the electoral uncertainty were Michigan’s 2024 split results, as voters there chose both Republican President-elect Trump and Democratic Sen.-elect Elissa Slotkin from the top-tier races. 

As for Whitmer, reports have viewed her as a top contender in the 2028 Democratic presidential contest, along with several other governors, like Pennsylvania’s Josh Shapiro, California’s Gavin Newsom, North Carolina’s Roy Cooper, Maryland’s Wes Moore, Illinois’ JB Pritzker and Minnesota’s Tim Walz.
