Chasten Buttigieg has gone viral on social media and supported his husband on the presidential campaign trail. Now, he’s playing a new role for Pete Buttigieg’s 2020 bid: rainmaker.

Chasten is slated to be the sole headline draw for several Pete for America fundraisers over the next month, starting with an event in Chicago this week. In October, Chasten will swing through New York City for another fundraiser, followed by a trip overseas to raise money from Americans living abroad in London on Oct. 22, according to event invitations obtained by POLITICO.

Chasten is also striking out on his own for other events, like a ribbon-cutting for a dozen new field offices in New Hampshire earlier this month, while Pete did the same for 20 offices in Iowa. The split-screen events show Chasten — a 30-year-old teacher who was nearly anonymous at the beginning of 2019 — cutting a campaign profile more akin to well-known former second lady Jill Biden than most 2020 spouses. And that prominence could be a force-multiplier for the Buttigieg campaign through the fall, keeping the fundraising spigot open while Pete stumps in all-important Iowa and New Hampshire.

"Chasten is as big of a draw for people who want to connect with the campaign as Pete, and that’s at all levels, not just high-dollar fundraisers,” said John Atkinson, a Buttigieg donor based in Chicago. And, he added, “to the extent that Chasten frees up bandwidth for the candidate, that is a competitive advantage."

Spouses can “speak for the candidate in a way no other surrogate can,” said Julianna Smoot, who led Barack Obama’s finance team in 2008, when future First Lady Michelle Obama became a national draw.

It’s no different in 2020. Jill Biden has also been aggressively deployed as a surrogate for former Vice President Joe Biden, both in public campaign events and private fundraisers, while Doug Emhoff, Sen. Kamala Harris’ husband, has also headlined his own fundraisers. Jane Sanders has played a critical strategic role in her husband’s political career, especially Sen. Bernie Sanders’ presidential runs. And Bruce Mann, Sen. Elizabeth Warren’s husband, occasionally lingers with reporters as he waits for his wife to navigate the often hours-long selfie line at the end of her campaign events.

But Buttigieg’s campaign is leaning on Chasten to a notable extent, playing off his rise to social media stardom by ramping up his public schedule since this summer. That has freed Pete to spend less time courting donors — which he’s done successfully, leading the Democratic field with nearly $25 million raised last quarter — and more time talking to voters in the early states, where the campaign is putting a heavy emphasis on building its infrastructure.

“He’s something of a secret weapon for this campaign,” Pete Buttigieg said in an interview with POLITICO. “One of the things you need to do on a campaign, especially when you’re new on the scene, is introduce yourself and convey your values to as many people as possible. Chasten, through his own story and his own approach and his focus on making sure that people have a sense of belonging, really embodies a lot of the values of this campaign.”

Chasten’s spousal status stands out especially in its history-making context: He appeared on Time magazine’s cover with an arm around Pete, under the headline “First Family.”

"Chasten is introducing America to what a same-sex couple looks like,” said Stephanie Cutter, a Democratic consultant, who served as Barack Obama’s deputy campaign manager and Michelle Obama’s chief of staff. “In that, he does a remarkable job of humanizing Pete, a candidate who is already very relatable.”

The Buttigieg donor invitations obtained by POLITICO show that Chasten’s events cater to a mix of high- and low-dollar attendees. Tickets for the Sept. 24 event in Chicago range from $25 for “young professionals” up to $500 to be a co-host and guarantee a photo. In New York, “Cocktails and Conversation” at a Manhattan residence will cost donors $500 to $1,000. Chasten has already held fundraisers in Miami, Tampa and St. Petersburg earlier this year.

Pete averages about $100,000 raised per event, while Chasten is expected to bring in about a third of that, according to a person familiar with the fundraising totals.

Though Chasten appears frequently in private settings for the campaign, he has kept a low profile with the media. In May, the Washington Post wrote about Chasten’s upbringing, including his stint as a homeless community college student in Michigan, and he sat for a rare interview on CBS’ “This Morning” alongside his husband — and their dogs.

Instead, Chasten, who took a leave of absence from teaching to join the campaign full-time, developed his own unfiltered social media presence. He tweets like the millennial he is, deploying well-timed gifs and pop culture insights to more than 380,000 followers. Last week, Chasten dropped a Lizzo lyric and a Bachelor reference in a single tweet about his dog, Truman, who has earned his own Twitter handle.

“There's a generational element to Chasten's appeal — creating a profile for himself on social media where we've gotten to know their pets, what they're doing on a daily basis,” Cutter said. “We can debate the role Twitter plays in our politics, but Chasten's feed has been a lens into who Pete is. Nobody else is doing that quite like Chasten.”

The massive field of candidates, coupled with the intense interest in the Democratic primary, may mean voters are “looking at [spouses] earlier in the process than we’ve seen in other primaries, and if yours is an asset — like the potential first husband — then you get him into rooms where he works best,” said Henry Munoz III, the former Democratic National Committee finance chairman.

Before he started headlining his own fundraisers, Chasten would frequently introduce his husband at events, retelling a story about their first date, when Chasten asked Pete if he had aspirations for higher office. Pete, who had run for state treasurer in 2010, responded: Maybe another statewide run in Indiana?

But by their first wedding anniversary, the couple showed up on that Time magazine cover and Chasten adds, “with a wink, ‘This isn’t what I signed up for,’” according to several Buttigieg donors.

The campaign has also turned Chasten into a draw for other groups’ events: On Sunday, he is co-headlining a champagne brunch fundraiser for the Victory Fund, the pro-LGBTQ group that supports political candidates and has endorsed his husband for president.

Some attendees might be attracted by “the novelty — ‘oh, it’s a husband’” on the campaign trail, said Annise Parker, the former Houston mayor who is now Victory Fund’s president.

But Parker added that Chasten offers a kind of alter ego to his husband, who can be “pretty buttoned-down, reserved, a bit introverted,” she said. “Chasten softens him up a little bit.”

Chasten has also proven to be an adept public speaker, particularly in front of LGBTQ audiences. At the DNC’s LGTBQ gala in June, Chasten replaced Pete for the keynote address at the last minute, after Pete returned to South Bend, Ind., when a black resident was shot and killed by a police officer.

“The entire room looked at him and said to each other, ‘Why isn’t this guy running?’” said Munoz, who hasn’t yet formally endorsed in the primary. “He plays the role of the spouse in a way that no one in American history ever has — and people want to meet him.”
