At the kitchen table: then vs. now

Prices & jobs over time

Pick something you care about, like gas prices or jobs, and see how it changed over the years. Each dot is a law Congress passed; tap one to see who voted for it. Gray bands mark recessions, and dotted lines mark major events.

Indicator

Pick a member of Congress to see how they vote, who pays for their campaigns, and what happened after the laws they supported.

Did new laws help?

When Congress passes laws on a topic, does the economy change afterward? This compares what happened in the months after those laws with what happens in an ordinary stretch of months. It shows what happened next, not proof that a law caused it.

The bottom line

Show the math

What happened, month by month

Every topic at a glance

The laws behind the numbers

Which party did better?

How did things go when Democrats or Republicans were in charge? Policies take time to work, so by default each month is credited to whoever was in power a year earlier. You can change that with the slider.

President by president

Follow the money

Campaigns run on donations. Much of it comes from PACs, groups that pool money from a company's employees, a union's members or people who share a cause. See who gives, who receives, and whether the money lines up with how members vote.

Where PAC money goes: groups → parties → members

Tap a group or a member to learn more.

Wider bands mean more money. "Other" groups together everyone else who got money from these groups. Politicians' own PACs (leadership PACs) and party committees are left out unless you choose them as the type of group.

Does the money line up with how they vote?

Each dot is a member of Congress. Left to right: where their campaign money came from. Bottom to top: how they vote.

Pick a group to see who it funds, who funds it, and whether the members it funds vote differently from others in their party.

About the data

Everything here comes from official public records: how every member of Congress voted, what became law, campaign finance reports, and government economic statistics. Nothing is estimated by us except where we say so.
