That's according to the People/Yankelovich POP Monitor Profiles, which measure the overall star power of 1,000 celebrities on 14 different attributes.
All three are "overexposed," and none are "believable," according to the index. On the question of whether respondents would "buy a product or service associated with" the candidates, only baby-boomer Clinton scored an above-average index, and then only among those over 50.
Clinton showed a clear advantage on one measure: all age groups would like to "spend the day with" him. After all, he is the president.
