Several recent studies concluded that constituent preferences have a s
ignificant impact on senators' roll call behavior on Supreme Court con
firmation votes, but the exact nature of this influence is unclear. In
this paper, Ianalyze analyze the Senate vote on Justice Clarence Thom
as using ideological, demographic, and electoral measures of constitue
nt pressures. The fact that both the interactive racial/reelection and
the ideology variables remain significant in a combined model confirm
s the importance of this matter for further research.
