For all intents and purposes, I think it fair to say that more people like Cameron than those that prefer Jon, this was bourne out at Jon's Eviction, I think also less people like him now than they did before, He has probably cost Nush the vote because of his attempts at influencing the public, and will cost Scott any chances of winning by his arrogance, considering that Jon is now effectively a paid lacky of C4/Endemol, as would any of the housemates that could of returned into the house.
Jon just has a very vocal minority that are blinkered in the belief that he is funny and entertaining, I never saw anything that could class him as anything but boring and arrogant, with large chip on his shoulder. Scott BigBrothers very own invisible man may have had a chance of winning but Jon has to interfere and attempts to garner public support, for the most inanimate housemate in BB history.
Ray to Win at least we know he is there 24/7 and is honest to himself and the other HM's, Cam the Sham has had more from BB4 than the others so he is not my choice as a winner, I would be neither upset or happy if Steph won.
