About Me

Hi, I’m Jake Marks, the creator of Polidex . I built this platform to make election forecasting and political data accurate, transparent, and easy to understand for everyone — not just pollsters, political junkies, or journalists. My goal has always been to break down complex data into clear, accessible visuals that help people see the full picture of how elections work and why they unfold the way they do.

I’m currently a student at the University of Southern California, where I study human security, geospatial intelligence, and political analysis. Polidex began as an academic experiment — a way to visualize polling data, political geography, and partisan behavior — but it quickly grew into something much larger. Today, it reflects my belief that informed citizens are the foundation of a functioning democracy.

I’ve lived in both liberal and conservative communities, which has given me a unique perspective on how Americans interpret politics. That experience shaped Polidex into something intentionally bipartisan and educational. My mission isn’t to push an agenda — it’s to provide clear, data-driven information that helps everyone, regardless of ideology, better understand the forces shaping elections.

Polidex is still growing, but its vision remains the same: to offer a nonpartisan, visually-driven space where data and analysis can meet real public understanding. I want Polidex to be a place where curiosity about democracy becomes something people can explore, not just argue about.

How Polidex Compared in 2025

Accuracy matters. Below is a quick look at how Polidex performed against other major forecasters in 2025’s key races — both in terms of projected margins and overall race ratings.

These results reflect what I’ve always aimed for — forecasts that are competitive with the biggest names in the field, but grounded in clarity, humility, and accessibility rather than hype. Polidex will always aim to explain before it predicts.
