The Santos house features three different staircases in three different episodes.
In the season 6 episode "Impact Winter", the staircase inside the front door to the house can be seen leading away from the door to the left of the hall.
In season 7, in the episode "Running Mates", the staircase can be seen coming down from left to right behind the door in a number of scenes,
Later in season 7, in the two "Election Day" episodes, the staircase has changed yet again, now curving upwards from the right of the door. Either Helen Santos has been doing some extensive remodelling, or different sets were used in each episode.
Senator Matt Hunt mentions an aircraft named the "3P-C Orion". It is actually called the P-3C Orion.
In the episode "The Ticket" (first episode seventh season) Annabeth corrects Leo how to pronounce "Santos". The assistant answering the phone in Congressman Santos' office apparently never got the same lesson because he pronounces it wrong in this episode.
When Farad asks Jed how old his children and grandchildren are, Jed tells him that Annie, Elizabeth Bartlet Westin's daughter, started high school last week. This does not fit in with the timeline of the series because Annie was twelve in the pilot.
Gen. Alexander makes reference to "The Kingdom of Syria", but Syria is a republic, not a kingdom.
When Leo and General Alexander are in the Situation Room, the monitor shows air strikes being launched. The voice over announces an F-14 launching while the monitor shows an A-6 Intruder moving towards the camera (which changes to an F-14 as it moves away). In the "real" world the A-6 is no longer in service with the US Navy.
Goof: Donna and Colin are drinking juice in the bar after just meeting. As Colin picks up his glass of juice, his fingers are at the top of the glass as he starts talking to her. As she replies, the camera focuses on her and now Colin's fingers are now on the middle of his glass.
In this episode, Donna visits the settlement of Kfar Darom. The issue of evacuation arrises, and the settlers say that they will never leave it because they believe it's their moral obligation to stay there. In reality, several years later the IDF began evacuating settlers in the settlements surrounding Gaza, and Kfar Darom was the last stand of the settlers, who barricaded themselves in a synagogue in town and refused to be removed from the town. Eventually, the IDF broke the barricade and evacuated the settlers by force.

Yossi, the Israeli border guard soldier Donna speaks with, tells her about two female soldiers who were killed by a terrorist in their barracks.
This is in fact a true story. On the morning of the 24th of October 2003, a terrorist acting in the name of Hamas and Islamic Jihad infiltrated the IDF base at Netzarim (near the Gaza strip), and killed two female soldiers in their barracks. Their names were Sgt. Sarit Shnior and Sgt. Adi Osman, both nineteen years old. Also murdered in that incident was Sgt. Alon Avrahami, twenty years old.
The uniform worn by the Israeli border guard was accurate rendition of an IDF uniform apart from the head-cap. Soldiers at border passings wear full protective gear - which includes a ceramic bullet-proof protective vest, and a helmet.
Mrs. Fitzwallace is called Gail in this episode, but her husband referred to her as Laura in "The Dogs of War".
Tularemia,Francisella tularensis, is known as Pahvant Valley plague, but is better known as Rabbit Fever and is not to be confused with what is generally known as The Plague (the Black Death, killer of 1/3 of Europe), Yersinia pestis, as seems to be implied by the doctor's reference to it in this episode. Its symtoms include fever, lethargy, anorexia, septicimic signs and inflammed lymph nodes that sometimes suppurate - which does look like the bubonic plague. The respiratory signs the doctor mentioned, however, are not associated with Tularemia or Bubonic Plague. Plague used to be said to have the bubonic strain and a respiratory strain (which was a more certain death than the bubonic) but that has since been disproved by analysis of Yersinia pestis. It is now thought to be likely that other illnesses contributed to the dramatic loss of life. Interestingly, in September of 2005 Tularemia was detected on the Mall in Washington, D.C after an anti-war demonstration. No infections were reported, however.
Although mentioned as a major media conglomerate, MertMedia does not actually exist.
*Season 6 spoiler* - The narrator of the show, which is supposedly broadcast after Bartlet leaves office, says CJ served two terms as press secretary. The writer didn't know that in season 6 she would be elevated to chief of staff, so it would have been more correct to say she served a term and a half as press secretary.
President Bartlet has nominated 3 Supreme Court justices, including Roberto Mendoza in "The Short List" from the first season, and Christopher Mulready and Evelyn Baker Lang in this episode.
Josh certainly has a jaded view of the Supreme Court. First, he says there are six centrists, two conservatives and Ashland, a liberal. That makes nine jurists, except that one of the conservatives has just died! Second, he seems to have forgotten that Mendoza, confirmed in the first season, was considered a hardline liberal. Either Josh is such a lefty he considers Mendoza a centrist or Mendoza actually compromised his positions and became one, which seems inconsistent with his character as established in the first season.
During the filming of this episode, PBS also filmed Stockard Channing, Allison Janney, and Lily Tomlin dancing to the song Boogie Woogie Sheep for their special "Sesame Street Presents: The Street We Live On," which first aired on Sunday April 4, 2004.
Alex tells Josh that the sky is blue because blue has the shortest wavelength of visible light. That's incorrect -- violet has the shortest wavelength.
When Toby and Gaines exit the Russell Senate office building, it's not the real one, but the Postal Museum near Union Station. The real Russell building is a lot closer to the Capitol, which can be seen far in the distance. The Dubliner restaurant is clearly seen in the close background with the Irish flag flying.
Josh went to Yale Law School.
