Monica had a good edit in the beginning, then she was portrayed as the challenge animal and even was a shadow for a couple of episodes... I think now she just gets a lot of attention aka screentime because she's the swing vote...
Like someone already said, she kind of has a Dawn edit so I would be very surprised if Monica managed to win or even get any votes :/ The only way Tyson wouldn't win is if the jurors really take into consideration his behaviour and the talking behind people's (Monica's) back.
