Professional reputation, unlike other components of Neustadt's preside
ntial power, has received little scholarly attention, The president's
professional reputation is the assessment of his performance in office
by the Washington community. According to Neustadt, president's profe
ssional reputation can be determined by reviewing judgments of his per
formance by those who collect, synthesize, and disseminate elite opini
on. We measure professional reputation based on the length and valence
of nearly 3,600 editorials and opinion-editorials in The New York Tim
es from 1961 to 1992. We compare these measures to previous operationa
lizations of the concept and test for convergent and discriminant crit
erion validity. This method provides a valid operationalization of Neu
stadt's concept of professional reputation, thus allowing for its incl
usion in more fully specified models of presidential power.
