The Leviathan theory of government was seemingly contradicted when the
U.S. Congress passed the Gramm-Rudman deficit reduction law. This stu
dy analyzes the Senate vote on Gramm-Rudman to try to determine whethe
r legislators acted in their own self interest. A prisoner's dilemma a
rgument explains how Senators made themselves better off by limiting t
heir own spending abilities. A probit analysis shows how voting for de
ficit reduction was consistent with the personal incentives faced by i
ndividual legislators. The eventual failure of Gramm-Rudman to elimina
te the deficit reveals a need to consider institutional as well as con
stitutional means of controlling government.
