For me the short list purely through the elimination of everyone else consists of : -

Darren:
Lovely guy who has conquered his demons, the John nom will only help him more. He is coming over very very likeable and decent if not the most dynamic.

David:
Mad as a box of frogs and has risen from the dead !! Who else can say that. Great fun and up for a laugh. Definitely a contender.

Gemma: Well it's the GC isn't it.. the shoe comment alone has her up there for me. Hilarious… great personality, gives it large in every way. Love her.

Scottie T: Personally not keen on him but harmless and far more likeable than Jeremy. Could see a big girlie vote getting behind him.

NOT A HOPE:

Nancy- lazy waster.. does nothing.
Kristina- the man robber who is now expecting will never get a vote to win
Angie- bonkers… no real fanbase.
John- arrogant manipulative, self righteous. The Darren nom alone has sunk him !
Megan - moaner, nothing endearing to garner a winning vote.
Stephanie - did the dirty on boyfriend outside.. thats her sunk
Jeremy - bloke she did the dirty with… thats him sunk..
Christopher - bland and uninteresting.
Daniella - borderline… will do well…. but not the win unless she is the dark horse.
Tiffany - not a hope… the rant may well have sealed her fate. no real fanbase .

Much to my surprise I'm liking Darren too and hope he makes the final.

Tiffany has gained a massive fan base. Plus bookies have noticed this to and she in the the top five now while John has plummeted

Nancy will win mark my words

Darren, Scotty T, or Gemma with a very small chance of it being Tiffany if she can keep the momentum going. how long is this series anyways?

Wasn't a fan of Darren, but would like him to win now. Impressed with him. I like Daniella and David. Liked John but don't trust him now. Don't like Tiffany, Stephanie, Jeremy, Megan, Nancy and Angie. Gemma is driving me nuts. Scotty, Kristina and Christopher are meh!

Tiff, Darren, Gemma, Jeremy and Danielle are up there

I think you've just called the final four.
