VIDEO : Stephen Colbert Uses 'Scooby-Doo' Reference For Democratic Debate

Stephen Colbert compared the Democrats running for president to an episode of ?Scooby-Doo.? In his parody, Scooby and friends were trying to find out which Democrat was hiding beneath a ghost costume. According to CNN, each member of the gang took turns guessing who it may be. Shaggy at one point says: "There's like too many middle-aged generic white guys, man!" Colbert often uses ?Scooby-Doo? comparisons, referencing the show when the Mueller report was released.
