You need Telly Addicts - current Strictly thread.
The betting will be based solely on popularity right now, not competence.
So you have Ellie first, because Chris won it last year and Rose a previous year. The British Public like to get behind someone who faces a more challenging journey on Strictly.
There have been many with additional needs/a disability, however, that did not win or even come close.
Jonnie/Oti, Will had to withdraw/Janette, Katie/Gorks, Ben/Kristina, JJ/Amy, Jody/Jowita, Lauren/AJ, Paralympian Ellie/Nikita.
This Ellie is a triple threat because she has the kids' vote (CBBC series), fashion vote (Vogue) and the underdog vote (the viewers will get behind someone who faces a greater challenge).
She has talked about Nikita and he is very popular/due a win according to his fans.
But she is short so may end up with Neil, the shortest pro. He is less popular with the public/public vote. Can't see her winning then unless she represents his redemption arc/turns around how the public view him (thirsty/attention-seeking/crap choreo at times).
Perceived fairness has nothing to do with it.
Or you'd have capped marks based on experience.
It has always been a popularity contest, first and foremost.
This is why George is second in the bets, due to his following.
Vicky is third as she has won IAC previously.
I'd be careful with your question though, as it may be interpreted as ableist, even if that is not your intention.
