Why, given a strong presumption of success, do some presidential nomination
s fail? Of 1,464 important nominations from 1965 to 1994, less than 5% fail
ed. Ninety-four percent of failures were rejected or withdrawn before reach
ing the floor suggesting that opponents are most effective during prefloor
stages. We propose a theoretical framework based on the notion that policy
entrepreneurs pursue their goals within the context of a presumption of suc
cess. Legit analysis tends to support the theory that entrepreneurs can alt
er the presumption of success and defeat a nomination if they (1) identify
negative information about a nominee to provide a rationale for changing th
e presumption and (2) expand the conflict through committee hearings and th
e media. Presidential resources-high public approval and efforts to signal
that the nomination is a high priority-increase the chances of confirmation
. Contrary to previous research, divided government has no independent effe
ct on the fate of nominations.
