At the national party conventions, state delegation breakfasts are in part organizational events, where weary state party staffers hand out credentials and preview the day’s schedule, not unlike camp counselors rallying their adult wards for the day. But the gatherings also offer revealing glimpses at political up-and-comers, who spend their early-morning hours with the party faithful they will need to secure higher office down the line. Their remarks are typically brief — sometimes funny, sometimes heartfelt, always laudatory of the state they’re addressing. For strong speakers, they end in standing ovations.

Savvy politicos make the rounds, moving with discipline from hotel ballroom to hotel ballroom and often hitting multiple breakfasts per day. Not all 50 are created equal: The A-list speakers pay particular attention to battlegrounds, influential delegations, and, of course, the early nominating states that could decide their fates should they pursue the presidency.

That elite status was clear this week for humble New Hampshire, with a breakfast speaker line up that included many of the party’s buzziest names. Vermont’s breakfast may have had maple syrup shots, but its New England neighbor heard from a who’s who of the party’s up and comers, including some who have run for president before or are looking to in the future, and some who were under consideration to serve as Harris’s running mate. Delegates enjoyed bacon, eggs, and potatoes as speakers addressed them from a podium flanked by inflatable coconut trees, an apparent tribute to the now-famous Harris line.

Not every state got the same attention. Shapiro was on the schedule to speak to a Massachusetts breakfast on Thursday, but did not appear. He did not miss his appointment with the New Hampshire delegation Wednesday morning, though.

The status of the state’s first-in-the-nation primary is uncertain on the Democratic side, after the national party pushed it later in the nominating calendar and New Hampshire rebelled. But the early contest, and the outsize power it gives this state of just 1.4 million people, was nonetheless at the center of the conversation.

“Speaking of New Hampshire, the primary is back!” laughed retiring New Hampshire Congresswoman Annie Kuster as she introduced Booker to the delegation on Thursday morning.

“I’m like, it’s home,” Booker said as he took the podium to applause. “I just love your state. I spent so much time there — I don’t know if you all know this, I ran for president in 2020.”

Ten minutes later, the crowd was on its feet applauding him, and state party chair Raymond Buckley had to chastise attendees for lining up for selfies and delaying the rest of the stacked program.

“You know, Cory Booker’s been to New Hampshire about 455 times, and he’s coming back,” Buckley chided.

For some of the state’s youngest delegates, access to the party’s future stars has been a highlight of the convention.

“Who’s gonna be there in ‘28, and who’s gonna be there in ‘32, and how many meals have we already had with them?” laughed Samay Sahu, a 20-year-old Dartmouth student. “Have I met them already? Have we taken a selfie?”

New Hampshire is “small” but “mighty,” Sahu added, crediting the primary for its political power.

Khanna, the California congressman seen as having presidential ambitions, attended more than a dozen state delegation breakfasts this week. A prominent poster near the New Hampshire delegation’s breakfast buffet thanked its sponsors; Khanna was at the top, and he was one of the few sponsors who did not live in the Granite State.

“I have gone to Michigan, to Pennsylvania, Wisconsin,” Khanna told reporters on Tuesday, naming a slate of battleground states as he spoke about the importance of introducing delegates to “the next generation of talent.”

“It’s about getting the right economic message for the party and figuring out what the right message is to win in the fall and going and talking to delegates, talking to people across the breakfasts, helps you figure that out,” he said.

And does the ambitious congressman have particular affection for the first-in-the-nation primary state?

“I love New Hampshire because it’s a state that values ideas. It’s a state that values retail politics,” Khanna said. He added that he has long been a supporter of New Hampshire’s first-in-the-nation primary, “and I’m pretty confident that it’ll have a big role going forward.”

Paying extra attention to states such as New Hampshire is nothing new in national politics. It was a similar scene at the Republican National Convention last month in Milwaukee, where onetime presidential hopeful Vivek Ramaswamy sponsored a breakfast for the state, his smiling face featured on posters outside the room. The state’s Republican delegation heard from Ramaswamy and Arkansas Governor Sarah Huckabee Sanders.

Bill Shaheen, husband of Senator Jeanne Shaheen and DNC committeeman for New Hampshire, said in an interview after breakfast Thursday that his state “has a tradition of being involved and being active, and I think we can help give these people who want to run for president guidance.”

Sahu, who introduced Boston Mayor Michelle Wu when she addressed the New Hampshire breakfast earlier this week, said he was “bawling” when they heard from Buttigieg, whom he reveres.

“The thing is, even though we’re seeing them, and I get to be, what, two feet away from Wes Moore, it’s almost not that big of a deal,” Sahu added. “Because he’s gonna come back to New Hampshire.”

LINCOLN, NH — There is “no longer an elevated risk” of contracting Legionnaire’s disease in Lincoln after seven people became infected by bacteria in a cooling tower in town over the summer, New Hampshire health officials said Wednesday.

Legionnaire’s disease is a bacterial pneumonia caused by inhaling water droplets contaminated with Legionella bacteria, the New Hampshire Department of Health and Human Services said. Initially, officials said that five diagnoses were made in June and July, but they added Wednesday that two additional cases have since been confirmed. All seven people were exposed to contaminated water droplets from a cooling tower behind the RiverWalk Resort downtown, according to officials.

The cooling tower underwent a cleaning and disinfecting process, after which testing conducted by the New Hampshire Department of Health and Human Services, Division of Public Health Services, and the New Hampshire Department of Environmental Services confirmed that “remediation efforts to eliminate Legionella bacteria were successful,” officials said.

The cleaning took place on Aug. 12, and water samples were collected for additional testing.

“Test results, which were received today, confirm the effectiveness of the facility’s cleaning and disinfection process with negative results for Legionella,” officials said Wednesday. “RiverWalk continues to partner with DHHS and NHDES on a water management plan to prevent future contamination or bacterial re-growth.”

The health department said it will investigate any other diagnoses with a potential link to the area.

“The negative test results received today are good news and demonstrate the effectiveness of the cleaning and disinfection of the cooling tower,” Dr. Benjamin Chan, New Hampshire State Epidemiologist, said Wednesday. “Therefore, we do not believe there is currently an elevated risk for Legionella infection from this cooling tower, and we will continue to monitor and work with the facility to ensure an appropriate management plan is in place to prevent future contamination or re-growth of the bacteria.”

Legionella are naturally occurring environmental bacteria that can grow in water systems and infect people who breathe in contaminated water droplets from showers, hot tubs, faucets, cooling towers, misters, and decorative fountains, according to health officials.

People and businesses can prevent waterborne germs from growing in water sources by properly cleaning and maintining all devices that use water, according to the Centers for Disease Control and Prevention.
