In offering Amy a Tahitian style cocktail, Josh refers to the rum as "Bacardi 451". Whew, definitely a Hawaiian Punch!
Note: There is no such drink called "Bacardi 451." There is "Bacardi 151" because of its proof. It is 75.5% alcohol by volume. It is HIGHLY advised to NOT drink this straight. It is recommended to mix with other beverages.
The flashbacks show Leo getting drunk in 1998. He must have been lying in "Take Out the Trash Day" when he said he hadn't had a drink since 1993.
Jordan says that Woodrow and Edith Wilson have been dead for eighty years, but Edith lived into the 1960s.
In a flashback, C.J. says that Bartlet has ten years on Hoynes. But in "Enemies", Hoynes says he is fifteen years younger than Bartlet. Presumably, C.J. was rounding off.
In the flashback scene where C.J. and Toby are tossing the basketball back and forth, when you look out the window behind Sam, it's snowing. In the window behind Toby, there is no snow.

Qumar is not a real country.
Goof: When Toby demands the ZIP code for Fargo, whoever looked it up for him got it really wrong. "50504" isn't a ZIP code for anything -- unless it's one of those fake TV "555" numbers. The most direct ZIP code for Fargo, ND, is 58103.
Josh keeps referring to the Dekalb County D.A., and he pronounces it as if the "L" is included, when in fact the "L" is silent in the Georgia pronunciation. We say "Dee-Kab" County down here.
Although in the past Georgia has executed children as young as 12 years old, under current law no one under the age of 17 can be sentenced to death.
Albie Duncan (Hal Holbrook) begins his recitation of similar incidents by citing the 1968 boarding and capture of USS Pueblo (AGER-2) by North Korea.
In 1973, Holbrook starred as CDR Lloyd Bucher, that ship's captain, in the TV movie "Pueblo."

The submarine reports its position as 36.6 degrees north, 110 degrees west - that's in Arizona, hardly off the North Korean coast.
Nancy, the National Security Advisor refers refers to the crew of the submarine as sub-mariners, pronouncing it like the comic book character or the baseball team with "sub" in front of it. The president later repeats this. While he might not know better, she should. The preferred pronunciation of submariners among Navy crews is to say it like submarine with an "r" at the end, like submarine-er.
Tawny Cryer was either joking or grievously mistaken when she stated that there's a Starbucks in Haight-Ashbury.
Josh refers to the "Indianapolis Post-Dispatch", which is not a real newspaper. The only daily paper in Indianapolis is the Indianapolis Star.
Continuity error - CJ says this is the President's first veto - however on episode 4 of season 2 on Capitol Beat (where Ainsley Hayes is introduced) the presenter says that the President veto'd a Republican education bill the year before.
As the Special Prosecutor reads off the names of the people being subpoenaed, he uses everybody's full name, but he nevertheless says "Toby Zachary Ziegler" instead of "Tobias Zachary",
