"In the evolution of the stories, politics and campaigning has been the arena least explored. We're trying to rectify that balance.""It's a slightly unreal element on the show that we haven't had the political sharks circling the White House. That dynamic will now be added." - Lawrence O'Donnell, Jr.

"That, we think, is interesting territory, when you look at who is likely to replace you and realize that you need to stay above the fray and, at the same time, you're not happy with the direction the election is going in," Wells says.

"It's giving us an opportunity to explore different points of view," he says, "and express in two actors different ideas that might have been a little bit difficult to express on the show over the years, because we are in a Democratic administration, the Bartlet administration, and so the Republicans are usually the enemy. No matter how favorably or with how much compassion you try to present that other point of view, you're trying to defeat them."In this, we now have a contest in which there's a discussion going on in which both points of view are presented. Oftentimes the Republican point of view sounds very, very compelling, particularly coming out of Alan's mouth."

"That's one of the issues that we're going to deal with. The real fear of Democrats in any election is that you would have a Republican who actually came from a more moderate state. The reason that we crafted this is, when we talked to the Democrats about the kind of person they never want to run against, it's someone like Arnold Schwarzenegger or someone from a large, typically Democratic state who's likely to carry that state. Because if you don't get the 52 electoral college votes out of California or out of New York, you're in trouble."
