I'm sorry if Malfoy did get placed in Gryffindor, the rest of the team would never vote him CAPTAIN they all hate him too much.
well, we don't really know how team captains are chosen, now, do we? Harry didn't vote for Angelina to become team captain, so I think it's fairly obvious that's not how it's done. McGonagall could be the one to make a choice, I don't know... but I think it's unlikely that someone with less experience would be captain if there's a more experienced player on the team. If I'm right about Malfoy going over to Gryffindor (Rowling did say that someone would change houses) and Ron having to fight to keep his spot on the house team (in a recent chat, she made it sound as though Ron will have a hard time getting to play quidditch) and Harry not playing quidditch anymore (I know he loves it, but he hasn't played for two years, I think his quidditch days are coming to an end) then it's quite possible that Malfoy, with his seniority on the quidditch field, would take over as team captain.
