The schoolteacher husband of presidential hopeful Pete Buttigieg is quickly becoming the favorite - over the spouses of senators Kamala Harris, Elizabeth Warren, Amy Klobuchar and Kirsten Gillibrand - in the race to become America’s first ‘First Gent’ in 2021.

Chasten Buttigieg, 29, whose husband Pete has suddenly taken the Democratic primary race by storm - would become both the youngest and first openly gay president if he succeeds.

And if the past couple of weeks is anything to go by, the former Chasten Glezman is the one to watch as his husband is soaring in the polls, looking a better bet to take on Donald Trump next year than any of the quartet of female senators who have declared.

Buttigieg, the two-term mayor of South Bend, Indiana, has caught fire with Democratic voters and raised $7million the first quarter of his long-shot campaign. He is now beating not only Warren, Klobuchar and Gillibrand in the polls, but also such high-profile male candidates as Beto O'Rourke, Cory Booker and Joaquin Castro.

Only two men — Joe Biden and Bernie Sanders, both more than twice his age — topped Buttigieg, 37, in last week's Emerson Poll of likely Democratic caucusgoers in Iowa.

And in a Quinnipiac national poll the Naval Reservist, who served a seven-month tour of duty in Afghanistan two years into his first mayoral term, soared to fourth behind just Biden, Sanders and Harris.

Chasten's quirky tweets about adjusting to life in the public eye have thrust him into the spotlight, making him a favorite prospective 'First Gent'

The Twitter humor of Chasten, a middle school teacher who is now director of curriculum at the South Bend Civic Theater, is being touted as much of the reason for Buttigieg's success.

'Chasten Buttigieg Is Winning the 2020 Spouse Primary,' blared a headline in Politico, which described him as 'a father of dogs, a Harry Potter fan, a theater geek, an enamored husband with a knack for choosing the right GIF' and in some circles, a 'folk hero.'

'Can one of the debates be an improv show?' Chasten asked, tongue-in-cheek on March 24.

Four days earlier he tweeted about having to adapt to a more public life. 'This new exposure can be very weird, and I'm not sure if I'll ever get used to teenagers taking pictures of me and then running away giggling when I look up and see them pointing their phones at me.

'This is why I can no longer smell deodorants at Target. They're always watching.'

Chasten also posts little snippets of how life has changed since Pete became a serious presidential candidate. 'Live from the Buttigieg household where one is on their second phone interview and the other is still trying to find his slippers...' he wrote at 5.19am last Wednesday.

During a tour of South Carolina, he wrote: 'Peter: Crushing townhalls in SC. Chasten: staring out the window waiting for UberEats.'

Chasten did not respond to requests for comment on this article.

He recognized his sexuality early and came out when he was 18, much earlier that candidate Buttigieg who waited until 2015 when he wrote a newspaper article just as the Supreme Court was deciding whether same-sex marriage should be legalized nationwide.

'I was well into adulthood before I was prepared to acknowledge the simple fact that I am gay,' the mayor wrote in the South Bend Tribune. 'It took years of struggle and growth for me to recognize that it's just a fact of life, like having brown hair, and part of who I am.

'Being gay has had no bearing on my job performance in business, in the military, or in my current role as mayor,' he added.

'It makes me no better or worse at handling a spreadsheet, a rifle, a committee meeting, or a hiring decision. It doesn't change how residents can best judge my effectiveness in serving our city: by the progress of our neighborhoods, our economy, and our city services,' he added.

Chasten is the youngest of three brothers brought up in a conservative family in Traverse City, Michigan. His father, Terry, runs a landscaping business.

When he came out he left home. 'I don't recall my parents specifically saying I couldn't live at home anymore, but I was made to believe I needed to leave,' he told the New York Times last year.

His mother Sherri told the Times: 'I don't want to say we were shocked. But, from our perspective, I was sad for him that, having two brothers that were into every sport, as roughneck as it comes, Chasten would be afraid of being perceived as different, or not as much of a man.'

He went to Chicago to get a Masters Degree in Education, earning money as a substitute teacher in Illinois public schools.

Pete and Chasten Buttigieg (pronounced Boot Edge Edge) would be the first First Couple to meet over the Internet. ‘I met him through this app called Hinge,’ said Pete. ‘As soon as I saw his picture, I saw something in his eyes. I said “I gotta meet this guy.” And then I did.

They had a lengthy courtship consisting of Facetime chats before bonding over a Scotch egg on their first date in the Fiddler’s Hearth Irish pub in South Bend in 2015.

‘Frankly, he’s one of the best things I’ve got going for me. I love him. He’s grounded. He keeps me grounded,’ Pete told CNN;’s Van Jones.

Pete admitted that being the mayor in a blue-collar city of only 100,000 people made dating difficult. He told the New York Times that his then-aim was to date 'a little outside the television viewing area of South Bend.'

On that first date, Chasten asked whether his new potential love interest played any musical instruments. Pete told him he had performed Gershwin's Rhapsody in Blue on piano with the South Bend Symphony Orchestra.

The response, Chasten admitted on Twitter, made him spit his beer on the table. In its review of the 2013 concert, the South Bend Tribune said Buttigieg had 'acquitted himself well as he executed the piece's difficult fast passages with technical precision, although technique sometimes took precedence over expressiveness.'

They married in the Episcopalian Cathedral of St. James in South Bend on June 16 last year.

Mayor Pete touts his diversity as a white man, telling an audience in Iowa: 'This is the only chance you'll ever get to vote for a Maltese-American, left-handed, Episcopalian, gay, war veteran, mayor, millennial'. Chasten came out to his family at 18, while candidate Buttigieg waited until 2015

The couple live in a white-columned, four-bedroom house overlooking the St. Joseph River in South Bend's historical district, that Pete bought for a bargain-basement $125,000 at the depth of the housing bust in 2009.

It is just around the corner from the house where he grew up, the son of two professors at Notre Dame University. His mom, Anne, still lives there. His dad Joseph, who immigrated from the Mediterranean island of Malta, died in January.

Pete and Chasten share their home with Truman and Buddy, their rescue dogs, both of whom have a huge social media following. Truman, born in Kentucky, was adopted in 2017 and Buddy, a one-eyed puggle, followed late last year.

So can Truman and Buddy join the long list of presidential pets, following in the pawprints of Bo and Sunny Obama, Barney Bush and Socks Clinton?

Or is Pete Buttigieg's 2020 quest for the White House doomed, like those of dozens of candidates who promised so much but burned out in the white-hot glare of the primaries?

'This is the only chance you'll ever get to vote for a Maltese-American, left-handed, Episcopalian, gay, war veteran, mayor, millennial,' he told an audience in Davenport, Iowa.

And, for a white man, that ticks as many Democratic boxes as possible.
