Congressional oversight
Contested roll calls on bills the Library of Congress files under Congressional oversight. Each member's score here is their whole-career share of those votes that sided with the Democratic majority.
Members on Congressional oversight
The 50 members with the most contested Congressional oversight votes, of 498 who have cast one and 0 with enough to score. A further 51 voted in the area but never on a contested question. Blue bars sided with the Democratic majority more often than not; red bars with the Republican majority. A dash is too few contested votes to score, never a zero.
