Scholars have argued that more restrictive registration laws,most drastical
ly deter the least educated citizens from political participation. Others,
however, argue that the most educated, rather than the least educated, are
most drastically impeded by restrictive registration requirements. These op
posing conclusions have dramatically different implications concerning regi
stration reform in the United States. In this analysis, we urge scholars to
take the arguments made by Nagler more seriously, and we argue that past m
odels have not fully considered the inherently nonlinear functional form of
the legit and probit models. Using graphical displays, we show that citize
ns with moderate levels of education are actually those who are "hardest hi
t" by restrictive closing dates. Consequently, we moderate all prior conclu
sions and show evidence that it is neither the most nor the least educated
who are the "hardest hit" by early closing dates.
