Leader-Follower ScoresThese representatives have the highest leader-follower scores. (View All Representatives)
To compute a leader-follower score for a Member of Congress, call him X, we make a table that lists all other Members of Congress. Each row has the number bills sponsored by X and cosponsored by the other Member of Congress divided by the number of bills sponsored by the other Member of Congress and cosponsored by X. This is a measure of who is following who. The higher the number, the more times others are cosponsoring X's bills without X returning the favor. We then take the mean of (the logorithms of) these ratios. Thanks to Joe Barillari for the idea.

(This plots the percent of Members of Congress ending their term in any given year who were present in Congress the following year.) The Political SpectrumGovTrack's own political spectrum analysis is another perspective on the behavior of our legislators. The analysis uses each senator or representative's pattern of cosponsorship to place them near others with similar patterns of cosponsorship.  | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
