For Michael it's about winning the confidence of the British public back, so I guess he would like to win BB, as this would be the ultimate symbol of re-acceptance.
I think Chantelle and Michael would be content not winning. For all the crap Dennis says about not giving a .... I think he would like to win. Pete is the one that truly couldnt care less. I'm guessing that George wants to stay as long as he can, though he probably knows he won't win.
Traci would love to win and dreams about it probably, Maggot doesnt care much either way.
Theres my opinions
