The current president of the Writers Guild of America, ER and West Wing producer John Wells, will not seek re-election in September. Likewise, the WGA's current vice president, Dan Petrie Jr.--who himself once held the position of president--will give up his post alongside Wells. Michael Mahern and Victoria Riskin are running for the presidency, according to the WGA's Web site. Riskin, a member of the WGA's board of directors, would become the WGA's first female president in 60 years if elected. Charles D. Holland and Don M. Mankiewicz are up for the vice presidency. There are 16 candidates running for the board of directors' eight open seats, including Polly Platt and Gregory Widen. The elections will be held Sept. 20.
