John Della Volpe

John Della Volpe is an American pollster, author, and advisor to Joe Biden's 2020 election campaign. He is the director of polling at the Harvard Kennedy School Institute of Politics and the founder of Cambridge's SocialSphere, a public opinion research firm focusing on Gen Z and Millennials. Della Volpe is also an MSNBC contributor.

Polling Della Volpe has conducted focus groups with Millennials and Gen Z voters. In 2015, Della Volpe described Millennials as "a more cynical generation when it comes to political institutions."

Gen Z Della Volpe has been called the "Gen Z whisperer." His book "Fight," published in January 2022, details the defining political issues of American Generation Z voters, as well as comparing the cohort to their Millennial counterparts. Della Volpe said Zoomers were distinct in a few ways from previous generations, notably a lack of political optimism for the future of America, a rise in anxiety and other mental health issues, and the group's then-nearly 2 to 1 support for Democrats over Republicans.

Book In January 2022, with St. Martin's, Della Volpe published his first book, FIGHT: How Gen Z is Channelling Their Fear and Passion to Save America. Publishers Weekly called it "the rare sociological study that manages to inspire," and it was an Amazon Editor's Pick in Non-Fiction.

According to Politico, Della Volpe said executive actions from Biden on "student debt, mental health, climate change" and the cost-of-living crisis would resonate among young voters ahead of the 2022 midterm elections.

Della Volpe commented in 2025 that the young male vote was not "lost" but that Democrats were "losing it right now." On a RealClearPolitics podcast, Della Volpe said young men were telling him that unaffordable housing was the most dominant issue and they felt that Democrats focused too much on celebrity endorsements.
