"The senator" has ABC's vote - or perhaps vice versa. Rob Lowe will continue on with the just-renewed Brothers & Sisters next season, and as a full-fledged cast member, Variety reports. Lowe first guested as Calista Flockhart's eventual love interest last November, then stayed on as a "special guest star" (which to me always reads as, "Good agent, better money").

My question: If Lowe's senator is elected president, does Martin Sheen come on as his deputy communications director? Is that how it works?
