Anna Wintour’s townhouse will be the hottest spot in New York this Tuesday. The reason for all the fuss is Barack Obama´s presence at the benefit dinner, sponsored by editor in chief of “Vogue”, in favor of the Democratic National Committee. According to “WWD”, Calvin Klein and Donna Karan are among those who paid around US$ 30 million to attend the event. Will the night help Obama raise his low approval ratings?
