With U.S. advertising agencies involved in the "selling of the President" since 1952, a number of firms, like California's Whitaker and Baxter, now handle only political accounts. And some candidates turn over their entire campaigns, from allocating expenditures to matching hairstyles with neckties, to public relations firms.
美國的廣告代理商從一九五二年起嘗試著去「推銷總統」，演變至今，有些公司完全以「助選」為業務，如加州的 Whitaker and Baxter 公司；也有些候選人索性將競選活動全包給廣告公司負責，大自經費的支配，小至候選人的髮型、領帶的搭配、上節目的化妝等無所不包。
