WHEN BARTLET SPEAKS, PEOPLE LISTEN -- When the President is overheard making a disparaging comment on an open-mike about the potential Republican nominee, C.J.does damage control for days after while Toby tries to finesse the newly named poet laureate from spealing out against the United States' lack of support for a land-mines treaty. Elsewhere, Sam recalls Republican White House legal counsel Ainsley Hayes from vacation to help spin the administration's response to Bartlet's gaffe; Josh is both repulsed and intrigued by the fact that he has his own fan-based Web site -- LemonLyman.com; the President also ponders an effort to save a failing giant computer company.
