The line forms here. As the Bartlet administration enters the last year, Oval Office hopefuls emerge from both major parties. And so do political strategists eager to back those bids for the White House dreamers and doers willing to leave their West Wing posts for another grab at the brass ring. An up-and-coming congressman (Jimmy Smits) and an astute Republican senator (Alan Alda) are among the Presidential aspirants. But in addition to the running for office, there's the business of running the country - a job on the shoulders of Bartlet (Martin Sheen) and his now reorganised staff. It's a taxing job under any circumstance, even more so when the nation's commander-in-chief battles the ravages of MS. The candidates, the staff, the nation: see how they run in this remarkable 22-episode Season 6.
