This title looks beyond roll call voting to examine whether bipartisan agreement in the House of Representatives has declined since the 1970s. Despite voting coalitions showing a decline in bipartisan agreement between 1973 and 2004, bill cosponsorship coalitions show a more stable level of bipartisanship. Declining bipartisanship over time in roll call voting reflects a shift in how party leaders structure the floor and roll call agendas. Party leaders in the House changed from prioritizing legislation with bipartisan agreement in the 1970s to prioritizing legislation with partisan disagreement by the 1990s, which the author feels reflects a changing political environment and an effort by leaders to balance members' electoral interests, governance goals, and partisan differentiation. The findings speak to questions of representation and governance. They also shed light on whether partisan conflict is insurmountable and whether bipartisanship in congressional politics is dead.
