In recent years, a number of studies have examined
the incidence of “killer amendments”—that is,
amendments that once adopted cause a bill that previously had
majority support to fail—in Congress. Yet most of these
studies have been either case specific, focusing on the legislative
maneuverings around a single issue or bill, or temporally limited,
focusing on strategic activity in only one or two Congresses.
In this paper, the authors begin a comprehensive
research agenda for the systematic study of killer amendments
in Congress. Using a dataset that codes each House roll-call vote
from the 83rd through the 108th Congresses (1953-2004), they identify
those bills that were successfully amended and subsequently went
down to defeat, a necessary condition for the existence of a killer
amendment. They then examine these cases in greater detail, using
both macro-level spatial analyses and micro-level case studies.
Their results indicate that killer amendments are rare, although
they uncover five cases, four of which are new, that appear to
fit the characteristics of true killers.
