The Effect of Race and Ethnicity on Bill Sponsorship and Cosponsorship in Congress

This article examines Black and Latino legislators' use of bill sponsorship and cosponsorship in Congress. As we explain, sponsoring and cosponsoring legislation are unique in that they are among the few activities outside the roll call arena that have both position taking and policy implications. We hypothesize that given minority legislators' lack of influence in Congress, they sponsor and cosponsor fewer bills than do nonminorities. We find support for our expectation; on average, Black and Latino legislators sponsor and cosponsor significantly fewer bills in Congress than do Whites and non-Latinos, respectively. But we also find the relationship to be contingent on which party controls Congress. Whereas Democratic Congresses encourage minorities' bill sponsorship and cosponsorship, Republican Congresses depress it. Because the concepts of participation and representation in Congress are so intimately tied to one another, these findings have a number of implications for the study of descriptive and substantive representation.
