Congress collaboration graph

Which members of Congress most often put their names on each other's bills. Members who frequently sponsor and cosponsor one another sit closer together and share a color, so collaboration clusters emerge from the data itself. This is a plain description of who works with whom on legislation — not a map of official caucuses, factions, endorsements, or anything to accuse anyone of.

Each tie counts the bills where one member is the primary sponsor and the other signed on as a cosponsor; ties are normalized so a few very active members don't dominate, then grouped into clusters and laid out so collaborators sit near each other. Learn more →
