The TCA winter tour brought at least one interesting piece of information for fans of the NBC drama ‘The West Wing’ – Martin Sheen announced he has almost finalized a deal to return to the show for half a season, enough to finish out his presidency. It’s no surprise to those with a passing knowledge of American politics that the end of Sheen’s President Bartlet’s second term will end his time as President, and one of Alan Alda or Jimmy Smits will succeed him in office. Executive Producer John Wells insists he hasn’t even decided which of the two will become President yet.
