Expect some good news and bad news in May for NBC’s The West Wing.  The bad news, obviously, being the end of the series and of John Spencer’s character.  The silver lining?  You will be able to catch up with a list of characters that have exited over the past couple of years.  Those expected to reprise their roles during the last few weeks include:  Annabeth Gish, Emily Proctor (now currently on CSI: Miami), Marlee Matlin, Gary Cole, Tim Matheson, Mary-Louise Parker and last but not least - Rob Lowe.  The finale will air on May 14.
