"Saturday Night Live" has a long history of parodying Presidential candidates (Chevy Chase as Gerald Ford. Dan Aykroyd as Jimmy Carter, Will Ferrell as George W. Bush. Fred Armisen as Barack Obama and Darrell Hammond as John McCain). And as a result, the show's influence is greater than it's been in years. In fact, the ratings have skyrocketed. The audience for the October 4 show, which followed the vice presidential debate, was up 42 percent from the comparable episode a year ago. "SNL" has even added a Thursday night "Weekend Update Special" to capitalize on the increased audience. And Tina Fey, who left "SNL" two years ago to write and star in the sitcom "30 Rock," has returned weekly. Check out a CNN interview with head writer Seth Meyers about the show's influence, and cast members Fred Armisen and Darrell Hammond about their respective portrayals of Barack Obama and John McCain.
