On the day of Mrs. Landingham's funeral, the staff deals with a Haitian presidential crisis and the law suit against the big tobacco companies, and Bartlet must decide about running for reelection.

Bartlet's decision about Haiti falls under scrutiny; C.J. makes a horrible blunder in a press conference and is hounded about the president's health by reporters; the staff disagrees about whether Bartlet should apologize for not revealing his medical condition; Abbey is angry that Jed has decided to run for reelection.

Election day finally arrives with the staff eagerly anticipating the outcome; Sam is increasingly concerned about the Wilde campaign in Orange County; Toby worries about the effect of Andy's pregnancy on the voters; Donna accidentally votes for Richie and tries to rectify the situation by trying to find someone who will vote-swap; Josh resists Deborah's new office rules until she reveals their basis; Bartlet has some new health issues to worry about.

While Toby and C.J. are in California working on Sam's campaign, Josh drops Abbey's agenda in favor of his own, Jed deals with a military hostage situation, and Will runs his intern writing staff ragged.

Toby's old friend approaches him ready to blow the whistle on his employer's violations of environmental laws; staff pranks abound on Amy's first day at the office; Abbey charges Amy with the task of convincing the President to threaten a veto on a foreign aid bill containing an abortion gag rule provision; claiming that Abbey's ancestor was a pirate rather than a privateer, a prominent member threatens to mount a boycott of the D.A.R. dinner at which Zoey will be inducted until Will, C.J. and Amy devise a plan to defuse the situation; at the behest of Jean Paul, Zoey sends Charlie a "Dear John" email, but Charlie refuses to accept the brushoff and declares his love for Zoey; Donna is less than thrilled when Josh assigns her the job of shadowing a possible security risk at Zoey's D.A.R. induction; Will takes one for the team in putting an environmental and political face on the destruction and deaths which resulted from the melting of an Alaskan glacier.

When Bartlet learns that Zoey's kidnapping is the work of Qumari terrorists, he invokes the 25th amendment to diminish their leverage and eliminate any conflict of interest; since there's no Vice President, the power of the Presidency passes to Bartlet's chief political rival and the most powerful Republican in the country, the Speaker of the House, who immediately takes a very hard line; now that twins Huck and Molly have arrived, Toby wonders if he's capable of loving them enough.

As the search for Zoey continues, Walken takes a hard line against the kidnappers that could contribute to her death; Danny releases the Shareef story, and the revelation creates a rift that separates Jed from Abbey and Liz; tensions arise between Walken's staff and Bartlet's staff; the Democratic leadership in Congress assails Leo for allowing Jed to step aside; in retaliation for Shareef's death, a movie theater in Turkey is bombed, and eighty people, including American soldiers, are killed.

Toby gets Jed's support to seize a controversial window of opportunity to save Social Security, but is hampered by Jed's mandate to keep the operation under wraps; desperate to feed the press corps beast on a glacially slow news day, C.J. meets with an attache to discuss cabbage imports, and has a little fun with a particularly dense reporter; Josh's brainstorm to help Will burnish Bob Russell's presentation problems and a persistent reporter endanger Toby's attempts to broker a deal on the Hill; Rina finds a friend in Donna, and Josh isn't too happy about it; Toby is saved from having to fall on his sword when Josh and Jed devise a plan to rescue his deal from certain disaster.

A documentary camera crew follows C.J. around for a not-so-typical day in the White House.

Hoynes throws his hat in the presidential ring, and asks Josh to join his campaign; Jed's health begins to deteriorate; Toby and Kate head the protocol negotiations with the Chinese over the arrangements for the upcoming summit, which is jeopardized when Jed mistakenly accepts a Taiwanese flag at the National Prayer Breakfast; Bernard takes his new position as head of the Gifts Unit to heart as he gives Charlie a hard time about retrieving the flag so that it can be returned; Josh has his hands full with a pro-Taiwanese senator holding a hard line on recognizing their independence; Bob Russell crashes an Oval Office photo op with the governor of Pennsylvania, who's also another potential presidential candidate.

The presidential candidates journey to Iowa, where democrats Russell and Santos, and republican Vinick, are all told by their handlers that when they appear before before the corn growers association they must support subsidies for the use of corn-derived ethanol as fuel, regardless of their true feelings.

It's five days before the New Hampshire primary, and Josh is desperately trying to find a "silver bullet" that will get his candidate into the local debate between the two front-runners, Vice President Russell and former Vice President Hoynes. Then, Josh and Santos's disagreements over how to run the campaign come to a head when Santos hires Josh's ex-girlfriend Amy Gardner to help him prepare for the debate he may never be in. And Donna has a memorable encounter with a chicken.

Santos is campaigning in California during the last few days before the all-important "Super Tuesday" primary elections, but he is out of money and he trails both Russell and Hoynes in the polls. When even "La Palabra", a Latino voters group, is all set to endorse Hoynes instead of Santos, Josh urges Santos to take a stand on the new bill that denies driver's licenses to illegal immigrants. Meanwhile, Donna tries to figure out why Hoynes suddenly isn't campaigning in California, and advances her position in the Russell campaign by becoming the Vice President's official spokesperson.

At the Democratic National Convention, Russell, Santos and Baker jockey for the 2162 votes that will give one of them the nomination for President, and the opportunity to lose to the apparently unstoppable Vinick in November. Meanwhile, the President must make a decision before it's too late on whether to deploy a secret rescue mission to the space station, and the FBI is asked to determine who leaked the existence of the military shuttle to the press.

Santos and Vinick have to deal with press fallout when it looks like the Bartlet White House is not going to continue the investigation into the press leaks.

Bartlet must deal with the possiblity of a nuclear explosion in California, Kate is keeping a careful watch on the election in Kazakhstan and China's response, Will is acting as the government's voice this week, and Josh is trying to keep his political version of Tourette's in check.

The Santos campaign meets up with Rock the Vote and lots of musicians are around for a star-studded episode. Helen gives a lecture to MANA (a National Latina Organization, formerly Mexican American National Association) but her heritage doesn't help her when trying to deliver part of the Santos campaign message. Toby is being pressured by the Attorney General, Blake, to reveal his source and it's affecting his relationship with his kids. He tries a little psychological warfare of his own to get Blake to back down. Toby is also giving Josh campaign advice which includes plans to increase courtship of the Latino vote. Elsewhere on the campaign trail, it's Halloween and Toby's kids and Santos' kids are dressing up for the occasion.

Election Day finally arrives, and between analyzing exit polls, and mulling over news reports, a few Santos staff members discover the joys of campaign romance. Meanwhile, C.J. ponders life after the White House; and Annabeth makes a tragic discovery.

Abbey is in New Hamphire with Liz Bartlet-Westin and they are awaiting the results of Doug Westin's campaign for a seat in Congress. Members of both the Santos campaign and the Vinick campaign must decide how to handle a tragedy, as the voters around the country continue to cast their votes for the next President of the United States.

While Santos is busy trying to select a new vice president, his wife finds her new responsibilities staggering. Meanwhile, Vinick ponders his next move.
