Is consulted by Toby and Josh in regards to dealing with a chemical company executive who wants to revise his written testimony to the House Committee on Natural Resources and seeks whistleblower protection, who Wayne reveals to the dismayed senior staffers is guilty of crimes and has to be granted immunity, leading Toby to later bitterly "praise" his old roommate and friend for making sure to have gotten himself out of legal trouble after his cowardice led to huge suffering for others.

Later a contender for the Republican presidential nomination in the 2006 election, though he never appeared on screen in that capacity.

  State governors

• Eric Baker : Governor of Pennsylvania. Widely tipped as a front runner for the Democratic nomination for president in 2006, Baker's surprise decision not to run at the outset leaves the race wide open.

  Campaign staff

• Bruno Gianelli : A sharp political operative and consultant introduced in the third season as the campaign manager of Bartlet's 2002 bid for reelection, and continues in this role through the fourth season. His unmatched track record of victories includes a House district that no Democrat has won for decades, several different U.S. senators and state governors, as well as a win for an unspecified Israeli prime minister. The character reappears as Eric Baker's campaign manager for the 2006 Democratic primary, only to become an independent consultant to Republican nominee Arnold Vinick after Baker withdraws from the race. The change of political affiliations mirrored Ron Silver's real-world change of party affiliation, as the noted liberal actor campaigned for President George W. Bush in the 2004 presidential election.
• Josephine "Joey" Lucas : A political consultant and pollster who is often hired by the White House and Democratic campaigns. Usually her interactions with Bartlet or Matt Santos are arranged by Josh Lyman, who has a crush on her early on. However, their relationship remains platonic and professional. Lucas first appears in the first season as the hard-hitting, sarcastic campaign manager for a Democratic House candidate whom the White House does not take seriously. She is then contracted to conduct a secret poll to determine whether the American public would accept the president's MS. Like Matlin, Lucas is deaf.
• Kenny Thurman : Joey Lucas's sign language interpreter.
• Connie Tate : Bartlet-Hoynes re-election campaign staffer ; a likable woman who quickly befriends Sam Seaborn. Often wins points by smoothing feathers ruffled by her acerbic co-worker Doug Wegland.
• Doug Wegland : Bartlet-Hoynes re-election campaign staffer and speechwriter ; he's acerbic and finds himself offside with Toby Ziegler, but ends up winning the staffers' respect with his good ideas and staunch belief in them.
• Kevin Kahn : Former friend of Sam Seaborn. Staffer on Ritchie's 2002 presidential campaign, who ends up humiliating Sam by leaking an attack ad that makes the Bartlet campaign look vindictive and stupid.
• Dylan Clark : Hoynes' campaign manager.

  Santos campaign

• Louise "Lou" Thornton : an intelligent lobbyist described by Santos as having a "completely different take on the campaign" and by Josh as knowing "image stuff backwards and sideways", she only reluctantly agrees to Josh's request to join the Santos-McGarry campaign as Director of Communications, when Santos agrees she can report to him directly. Very tough and experienced, she successfully argues that many loyal Santos campaign operatives are not up to snuff and gets them cut loose, and later tells Josh she has run Democratic campaigns that destroyed the careers of smart, well-intentioned Republican candidates because they're still the GOP and the enemy of what she believes is right. With Josh considering her to have enough campaign experience to potentially replace him as Campaign Manager, she acts as Josh's de facto deputy through to the very end, and at Josh's persuasion, accepts her appointment as Santos's Director of Communications.
• Ronna Beckman : Santos's personal assistant. She is present from the very beginning of Matt Santos's campaign for the presidency in season 6, and appears in almost every episode in season 7, as Lou considers her work good enough to continue. In one episode, she mentions that she regards Josh, Annabeth and Lou as her only friends, which Lou claims makes Ronna more pathetic than herself or Annabeth. In her final appearance, Deborah Fiderer trains her as Santos's executive secretary, warning her never to revoke the First Lady's walk-in privileges, even as the President is certain to request it. She has a relationship with another female staffer on the Santos campaign.
• Edie Ortega : Santos-McGarry Deputy Campaign Manager for Strategic Planning.
• Lester : Santos-McGarry Campaign Consultant.
• Bram Howard : Staffer, Santos-McGarry Campaign ; Santos Administration counselor to the President. Moves into Charlie Young's former office on Inauguration Day.
• Ned Carlson : A day-one aide to Congressman Santos ; Staffer, Santos-McGarry Campaign. Has somewhat of an adversarial relationship with Lou, who highlights Ned as a staffer who is not up to the demands of a national campaign and says he needs to go precisely because he's a trusted assistant to Santos. Ned is reassigned by Josh to Santos's Congressional office early in Season 7 with the intention of giving him a spot in the administration after the election. Ned angrily tells off Josh and it's left unclear if he's quit the entire campaign or not. He does not appear after his demotion takes place.
• Otto : Speechwriter, Santos-McGarry Campaign ; Staffer in the Santos Administration. Very young but capable man who has a campaign fling with Lou Thornton. Josh irrationally vents his post-election stress and anger at Otto, who is saved when Sam Seaborn shuts Josh's behavior down permanently; it is implied he will have a speechwriting role in the Santos Administration.

  Vinick campaign

• Sheila Brooks : Senator Vinick's chief of staff and Vinick-Sullivan campaign manager; She, like Vinick, is portrayed as level-headed and not overtly partisan. Often at odds with the more conservative voices in the party, she leaves the campaign weeks before election day to placate the Republican base. In her final appearance, Brooks is mentioned as possibly being hired as Chief of Staff to the Republican Senate Majority Leader. Having renewed her friendship with Vinick, she makes an argument that convinces the Senator that he shouldn't run for president again—and that he should accept President-elect Santos' offer to become the next Secretary of State.
• Jane Braun : Vinick-Sullivan campaign manager after Brooks' resignation ; A far to the right conservative activist who replaces Sheila in order to energize hard-core GOP voters. However, she disgusts the rest of the campaign leadership by attempting to make an election night issue of Leo McGarry's death. Her outspoken partisanship puts her at odds with Vinick, Sheila, and Bruno Gianelli.
• Bruno Gianelli :.
• Bob Mayer : Vinick-Sullivan speechwriter. Frequently mocked for his messy eating habits but extremely smart and effective, Mayer becomes fast friends with Gianelli. On election night, the two briefly discuss forming a consulting firm when Mayer firmly declares he is never going to become involved in daily governance, but Gianelli politely declines because the campaign life has worn him down and he plans to retire to his home in upstate New York. Along with Sheila, Bob advises Vinick to accept Santos' offer as the next Secretary of State.

  Media

• Danny Concannon; : senior White House correspondent for The Washington Post.
• Greg Brock : White House correspondent for The New York Times. Greg Brock is also the name of a real editor for The New York Times. One of the most regularly referred to White House correspondents, second only to Danny Concannon. Writes a story that alleges the existence of a classified military space shuttle which could be used to help three astronauts on the International Space Station who are running out of oxygen. His source is initially suspected to be C. J. Cregg, whose phone records show a surprisingly large number of calls to Greg Brock. Brock goes to jail after being held in contempt of court for failing to reveal the name of his source. White House Communications Director Toby Ziegler eventually confesses to the leak, saying that he acted alone, and that Brock was the only reporter to whom he leaked the information. The storyline regarding the leak and subsequent investigation has been compared by some to the Valerie Plame affair..
