Whenever a new president is elected, tabloids and journals bump sales by profiling the arrival of the next "First Family." Women's clothing choices, children's behavior, couples' tenderness or standoffishness are duly chronicled. Some First Families create idyllic portraits of the closest thing Americans will have to royalty (the Kennedys and "Camelot"). Others bring homespun commonness into the White House (the Carters). A few depict dynasties in the making (the Bushes, first and second), while yet others seem to leap off the silver screen and bring Hollywood to life (the Reagans).
