"The effects of sexism and racism on popular attitudes and behavior have long been recognized. More recently, another prevalent, bias, ageism, has become a topic off concern and inquiry (see, e.g., Butler, 1969; Harris and Associates, 1975). However, surprisingly little is known about the impacts of sexism, racism, and ageism on political behavior, and more specifically on voting decisions, These are issues of growing concern as women and members of racial minorities become increasingly active in electoral politics; the issue of age was also brought to the fore recently by the presidential candidacy of the 69-year-old Ronald Reagan. This paper uses an experimental approach to explore the extent to which and the manner in which the sex, race, and age of candidates for political office affect voters' decisions and the extent to which such influences are contingent on characteristics of the voters. Most of what is known about the relationship between candidate characteristics and voter preferences is derived from opinion surveys in which respondents have been asked questions like "If your party nominated a woman for President, would you vote for her if she were qualified for the job?" These surveys reveal an increased willingness over the least 25 years to vote for a qualified black or woman for President, with indications that voting discrimination against blacks began to fade somewhat earlier than it did against women (Ferree, 1974; Schreiver, 1978)."
