"What we're hoping to do is give the audience some insight into what the campaign process is about," Smits says.

"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.

"The West Wing is doing an interesting experiment here," [Alan] Alda says. "If it ends up being Jimmy Smits' character versus me, we'll have a contest to see who can present their arguments better, not who maneuvers better."

Wells felt he wasn't playing sides in the campaign by crafting a good guy/bad guy scenario. "We've set up both candidates as someone you'd like to have a beer with," he said.

One "candidate" who thinks he doesn't have much of a chance is Cole. "Bingo" Bob Russell, says Cole, "knows how to run a race, but if he gets it, who knows? But I don't think he'll have to worry about that. Look, they'll enter next season with two guys running in the presidential campaign. I'll let you figure out who those two guys might be, and I don't think you'll need to be Dick Tracy to do that."

"All of us players who have been involved this season will be part of next season, in some form or another," Smits confirms. Regarding his chances of beating out Alan Alda to succeed Martin Sheen as the prez, he says, "My hiatus will be a little bit like, 'Hmm... I wonder, wonder, wonder.' I'm OK anyway it goes. The way [executive producer] John Wells set it up, there's so much fodder for story lines that could happen, and we're all up for that."

Talking to executive producer John Wells shortly after the real-world 2004 political conventions were held, both remarked on how carefully controlled and sterile the events were (with the exception, Smits says, of Barack Obama's rousing speech)."The Democratic convention on 'West Wing' will be more reminiscent of Chicago but not in terms of its violence. There's going to be a convention, not a slickly produced television show," he said.

For its season finale Wednesday, "The West Wing" comes west to San Jose. Well, in looks, anyway. You'll recognize the site where the TV series' fictional Democratic National Convention is supposed to be choosing its next presidential candidate: HP Pavilion. "Warner Bros. called last week to get permission to use exterior shots of the arena," reports Tom Manheim, the city's outreach manager. "For this week's show. I guess that shows how tight their production schedule is." And how perfect the Shark Tank would be for a gathering of politicians.
"'West Wing' coming west to San Jose"

As a former VOTE-COPE chairperson and current local leader, I struggle with my members about the importance of our VOTE-COPE programs both statewide and locally.After viewing the season finale of "The West Wing," I now have new ammunition to prove that VOTE-COPE makes a difference. The episode showed a Democratic convention in chaos over choosing the successor to the outgoing president. After several rounds of balloting, there seemed to be no hope for consensus.
In discussing who delegates would vote for in the next round, it was stated that the New York delegation was led by a member of the teachers union. One conversation in the episode stated what we know: Teachers' and labor unions' support have been the bread and butter of the Democratic Party. What a fitting tribute to VOTE-COPE and our retiring President Hobart that a television writer acknowledges the political activism and power of our union. VOTE-COPE matters, and it makes its presence known in some amazing places.

In Season 6, the show really found its feet again...It took a while for us to figure out what the hell we were going to do! I think the show is now more of a reflection of the real world as opposed to a fantasy of what it could be, but still keeps the intergrity of the characters.
