Discussions of public opinion are dominated by visions that regard it
as a rational ideal or as an objective datum. The evident differences
between these interpretations reflect distinct ideologies and disparat
e scholarly and research interests. Without gainsaying their consequen
ces, attention to these differences has muffled their shared illuminat
ion of public opinion as a product of discourse. Even when they give d
iscourse thematic priority, rhetorical norms become buried amidst the
rationalism of ideal communication or the instrumentalism of degenerat
e manipulation. Neither characterization shows satisfactory empirical
fidelity to the complex process whereby public opinion is formed and c
ommunicated because neither accounts for the dialogical engagements by
which an active populace participates in an issue's development; the
contours of the public sphere that color their levels of awareness, pe
rception, and participation; the influence an opinion formation of sha
ring views with one another; and the terms of expression warranting th
e inference that a public has formed and has a dominant opinion. This
essay develops a rhetorical model that emphasises the discursive endea
vors of those whose symbolic formations in everyday ''talk,'' or verna
cular rhetoric, authorize public acts and conduct taken in their name.
