Character mistake: Both in the title and throughout the episode, people refer to 'Lord John Marbury'. However, the first names of peers are not used when also using their titles; so Marbury should be called either Lord Marbury (more accurately Earl Marbury), or just John Marbury. A minor error in the real world, but the White House is supposed to be aware of diplomatic eccentricities like this.

Genres: Drama
Election Day (Part 1) - S7-E16
Continuity mistake: When Bruno and Bob are poring over exit polls, they mention that Santos seems to be leading in North Dakota, and comment that it is a state that hasn't gone Democratic in forty years. While that is true in the real world, in the fictional West Wing world, it is stated in Season 4 that Bartlet won the Dakotas in his landslide reelection.
Laurie: Tell your friend POTUS he's got a funny name, and he should learn how to ride a bicycle.
Sam Seaborn: I would, but he's not my friend, he's my boss. And it's not his name, it's his title.
Laurie: POTUS?
Sam Seaborn: President of the United States.
Trivia: Martin Sheen's daughter, Renee, plays President Bartlet's assistant Nancy. Since she doesn't use her father's stage name, Nancy is credited by her birth name "Estevez."

Answer: It's in reference to the many televangelists and revival ministers usually associated with the right-wing that have been convicted of tax fraud (Jim Bakker and Tamy Faye being a more famous set). Occasionally, the more unscrupulous ministers have bilked millions from believers all in the name of God.
