We develop a theory of smoke screening (ambiguity) as a means of maxim
izing political support when the voters' evaluation of a candidate dep
ends on the quality of information they receive, on their ability to o
btain and process relevant information and finally on the candidate's
popularity (goodness of reputation). We show that the more favorable a
candidate's standing relative to his competence the greater the incen
tive to milk good reputation by generating smoke screens; and that the
more ''savvy'' (educated, knowledgeable, involved etc.) the public th
e lower the amount of smoke screening activities undertaken.
