In the first chapter in Part III, Frances Lee shifts the focus from elections to governing in the context of contemporary American politics. She examines the strategies of coalition leaders in Congress, who now operate in a world of highly polarized congressional parties. She scrutinizes the two major legislative efforts of the 115th Congress (2017-18): tax reform and the repeal and replacement of the Affordable Care Act. Lee finds that coalition leaders used many of the same techniques as in earlier periods. In particular, coalition leaders substantially modified their proposals to reduce the costs imposed on the constituents of legislators whose votes they needed. Similarly, leaders deployed procedural tactics to break the linkage between Congressional action and painful policy effects. These efforts were successful on tax reform but ultimately failed with the efforts to repeal the ACA, and Lee finds the failure was related to the traceable costs of the proposed policy change. She concludes that although polarization has arguably created new challenges for enacting major legislation, the strategies of coalition builders exhibit a good deal of continuity.
