Objective. This study examines the ''congressional dominance'' model t
hat is popular in the policy process literature. The purpose is to det
ermine its explanatory power when the model is extended to include bot
h the House and the Senate (rather than the current fascination with j
ust the Senate), acting through both the appropriations and the oversi
ght processes, in contrast to the literature's focus on so-called ''in
dependent'' regulatory commissions. Methods. Using measures of legisla
tor preferences and agency output, this research uses multiple regress
ion to detect congressional influences on U.S. Forest Service outputs.
Results. While congressional preferences do have detectable influence
on Forest Service outputs, the overall influence (as indicated by mod
el R(2)) is practically nonexistent. Conclusions. The results call the
''congressional dominance'' model into question, indicating that futu
re efforts aimed at explaining policy outcomes would do well to extend
the examination to include other actors in the process.
