This paper examines the degree to which legislative leaders in the mod
ern era are expected to expend energy on public relations, campaign ac
tivities, and interaction with other government officials, perhaps at
the expense of more traditional institutional activities. Using data f
rom 120 senators in three state legislatures, the author examines an e
mpirical model in an effort to explain variations in the proportion of
external activities associated with legislative leadership. Empirical
tests reveal a statistically significant relationship between a legis
lator's institutional, electoral, and personal environments and the ex
ternal nature of the individual's expectations of legislative leaders.
However, characteristics of a member's personal environment-primarily
experience, ambition, and role orientation-are most strongly related
to how that member defines appropriate leadership. The vocal and visib
le legislative leadership of modem legislatures is encouraged by young
, ambitious politicos who perceive themselves as electorally vulnerabl
e. This tendency is particularly strong for legislators of the executi
ve's party in competitive institutions. Leaders will continue to focus
attention on external activities as long as members perceive such act
ivity as being in their own interest.
