Chelsea, Ugly Betty, and Joan of Arcadia

Kate Snow of ABC's Good Morning America describes how Chelsea stepped up to help Mom clinch the Nevada caucus:

ABC News' cameras were allowed to follow Clinton as she campaigned in Nevada, joined in a nondescript minivan by Amber Tamblyn, star of "Joan of Arcadia," and America Ferrera, better known as the title character in ABC's "Ugly Betty." The famous trio's hectic day began with a rally, and her father, former President Clinton, and retired NBA basketball Magic Johnson, were along for the ride.
