S1E6 · Mr. Willis of Ohio

Complete story — includes the ending

The senior staff and the President take part in a late-night poker game inside the West Wing. A social studies teacher from Ohio finishes the term of his late wife in the United States House of Representatives while Sam tutors C.J. about the U.S. census, and the staffers seek crucial votes in favor of a bill to use statistical sampling which will be more accurate, and free funds for other uses. Zoey has an unfortunate encounter in which she needs the help of the U.S. Secret Service while at a Georgetown college bar in the company of friends from the White House. This displeases her father, who lectures her about "the nightmare scenario" – the possibility of her abduction being used against the government. Later the staff and the President sit down to another poker game while Toby watches the end of the roll call for the bill. Note: The "nightmare scenario" mentioned in this episode becomes a reality in Season 4 episodes 22 and 23, continuing through Season 5 episodes 1 and 2 when Zoey Bartlet is indeed kidnapped.
