Legislation is how ideas are put into a format that Congress can process and transform into law. Some ideas are introduced again and again, but in different formats or at different times. Some bills in one chamber of Congress may have a nearly identical version introduced in the other. The same bill can be introduced again and again over multiple Congresses until it is enacted into law. Or a group of legislative ideas can be rolled together into a larger legislative package.

I like to think of ideas contained in legislation as legislative memes, which is a powerful way to understand what Congress is doing. We are working on a legislative tool, call BillMap, that allows you to track legislative memes as they move through Congress.
