Isaac Horwitz

Pronouns: He/Him/His

Political advocacy began for Isaac at age five when he wrote a letter to President George W. Bush urging him against the war in Iraq (and received, in response, a signed photo of Bush’s dog, Barney). Since then, Isaac has been passionate about the intersection of politics and data.

As a key member of the data team at GSG, Isaac leads analytics work on quantitative projects—including the DNC’s 2024 research on behalf of Harris for President, GSG’s collaboration with the Hub Project on Navigator Research, and polling for U.S. Senate candidates across the country. His work includes building models, programming surveys, processing data, and delivering insights.

At GSG, Isaac is also a leading contributor to internal methodological research. He has supported the firm’s initiatives to better understand and address the drivers of survey nonresponse, and he is actively involved in a project exploring the potential applications of artificial intelligence in quantitative research.

Before joining GSG, Isaac served as a data fellow for down-ballot Democratic campaigns at Bluebonnet Data. Isaac graduated from Columbia University with a B.A. in Political Science and Statistics, where he conducted research using natural language processing to study the relationship between far-right tweeters and real-world political violence.

When not crunching numbers, Isaac enjoys biking in his native city of Santa Monica or maneuvering the subway (a.k.a. getting lost) in unfamiliar neighborhoods of NYC.
