Who Runs Congress: An ASCII Maps Project

Here’s a paradox for you: the most powerful people in Congress are the ones most Americans have never heard of.

Cable news covers the floor — the speeches, the walkouts, the C-SPAN theater. But the floor is the last stop, not the first. By the time a bill gets a floor vote, the real decisions have already been made in committee: what gets a hearing, what gets marked up, what gets quietly buried, who gets subpoenaed, and who never has to answer a single question under oath. The committee gavel is where the power lives. Everybody in Washington knows this. Almost nobody outside of it does.

So let’s map it. All of it.

This is the full committee and subcommittee leadership of the 119th Congress as of mid-2026: both chambers, every standing committee, every select and special committee, the four joint committees, and — the part nobody bothers to compile — every subcommittee, with its Republican chair and Democratic ranking member. Over 100 panels. Because Republicans hold both chambers, every gavel is a Republican hand; every ranking member is a Democrat (or an independent caucusing with them — hi, Bernie!).

It comes in two flavors:

• The infographic (above) — the visual overview for scanning who holds what.
• The ASCII tree — a plain-text, monospace map with the complete roster down to the subcommittee level, including mid-Congress successions and the seats I couldn’t verify (flagged, not guessed). It’s diffable, terminal-friendly, and pasteable anywhere. Check it out below the break, and in my Github plain-gov repository where I’ll be adding more of these “just the facts, ma’am” maps.

Why this was harder than it should be

You’d think a single, current, complete roster of committee leadership would exist somewhere official. It doesn’t — not really. The data lives scattered across dozens of individual committee websites, updated on their own schedules, with subcommittee gavels shifting mid-Congress far more often than the full-committee ones. The House Intelligence Committee doesn’t publicly publish a per-subcommittee leadership roster at all. One Ways & Means subcommittee literally has two different names depending on which party is saying it.

That opacity isn’t a bug. A public that can’t easily see who controls the machinery is a public that can’t easily hold the machinery accountable. The system isn’t broken — it’s working exactly as designed. Which is precisely why the map is worth making.

What to do with it

Find your issue. Find the subcommittee that owns it. Find the two names on that line — the chair who decides whether it moves and the ranking member who decides how loud the opposition gets. Those are the people to watch, call, and pressure. Not the loudest voice on your feed — but the one holding the gavel.
