This article revises our understanding of the conditions under which t
he federal government produces important legislation. I reevaluate and
only mildly vindicate Mayhew's findings about the effect public opini
on has on the productivity of the federal government. By revealing the
size of the nation's debt to be an important determinant of productiv
ity, however, I suggest that Mayhew's work overlooked the relationship
between fiscal conditions and policy output. I also examine empirical
ly the claims of Krehbiel's theoretical work about gridlock.
