I understand why Draco wouldn't support Harry¹, but I don't understand why he wouldn't throw his support to Cedric, a fellow Hogwarts student, a well-liked guy in general, and also a Seeker, like Viktor, Harry, and Draco himself. I glanced through Goblet of Fire, but didn't find anything particularly compelling that would explain why Draco would choose to support Viktor over Cedric, aside from the Durmstrang students sitting at the Slytherin table for the welcoming feast after they first arrive at Hogwarts.
Is there a specific reason cited for Draco supporting Viktor in the Triwizard Tournament in Goblet of Fire?
¹Potter stinks?
