S6, E18: Santos (recurring guest star Jimmy Smits) travels to Sacramento, California, for the last few days before Super Tuesday (a day when a large number of states simultaneously hold their primary elections; the single day when the most nominating delegates can be won). While he's trying to gather support for his healthcare agenda, Santos is pressured by the media to reveal his stand on California legislation that would provide driver's licenses to illegal immigrants. Russell (recurring guest star Gary Cole) decides not to go to California, and Hoynes (recurring guest star Tim Matheson) capably dodges the issue. Meanwhile, Donna takes a more proactive role in the Russell campaign by becoming the new spokesperson.
