What the rankings mean:

Number of bills sponsored:

This metric measures the number of unique bills put forward by a Representative or a Senator. A Resolution usually expresses an opinion or addresses procedure in the House or Senate and doesn’t go to the President. An Amendment is a change to the language of legislation. Everything has to be voted on.

Number of bills passed out of one chamber:

Getting a bill passed through a chamber is tough. In order to pass a bill out of a chamber, a member of Congress must build consensus among his or her colleagues.

Number of bills signed into law:

If a bill from an opposite party is signed into law by a President, the achievement is a significant victory for that Member of Congress if the bill is significant. Many non-controversial bills are signed into law as a matter of routine.

Percentage a member votes with his or her party:
