"What you will see is the new speaker, the majority leadership (Republican) and their views much more represented on the show," Wells told reporters in a conference call last week. "Our characters aren't changing, but the world in which they live forces them to hear the other points of view."

"The powers that be at the White House see an opportunity to put their own chief justice on the bench, but they have to be very delicate about it," said Perry. It's an episode not just about power but about the longtime relationship between the chief justice and Perry's character....
"I think 'West Wing' is as good as it was ... which is an amazing accomplishment given the genius of Aaron Sorkin," Perry said. "I would say it's slightly more of a team effort over there."...
He worked most closely this time with Richard Schiff, who plays communications director Toby Ziegler.
"He's a talented and nice man, and he made it fun. Maybe Richard Schiff and I will go on the road together and do a little vaudeville or something," he said, jokingly.

He showed a great deal of candor and passion for the show during his talk, and had a good feel for (and devotion to) the show's history; the writing staff is always on guard against repeating themselves (e.g. they wouldn't have done another Supreme Court arc this season without bringing new angles to the table)
