S6, E20: After winning the Republican nomination for presidency, Arnold Vinick (recurring guest star Alan Alda) begins working on his campaign. Bruno Gianelli (recurring guest star Ron Silver - "Ali"), a political strategist, gives the Republican candidate advice about choosing a vice president and handling Vinick's latest controversy--his failure to attend church. Meanwhile, the Democrats are stuck in a three-way race for enough delegates to win the Democratic nomination; Russell (recurring guest star Gary Cole) barely leads Santos (recurring guest star Jimmy Smits); and Hoynes (recurring guest star Tim Matheson--not appearing in this episode) is now a distant third. Bartlet tries to show unity in the party by wrangling the candidates.
