Sadly I think there are a lot of casual viewers who likely don't tune into the stream and only see how she's portrayed on the daily shows, and she's been getting a super positive edit recently. They're milking the "I need this money for my kids" (by the way, did you know she had three kids?) sympathy edit and hiding all of the two-facedness, the stashing of food and coffee and just her all round unpleasantness
Let's not forget how she was adamant she wouldn't kiss anyone while in the house and on national TV (again, she apparently has morals and she's doing it for her kids), and yet for the past week and a half she's completely backtracked on that as well. Unfortunately, a lot of the casual viewers love the showmance crap, and she's worked that out (cf Holly and Colin) and decided to jump on that train.
A Coco win wouldn't be any better than a Colin win in my view, but sadly I feel that if it's not going to be Colin, it's going to be Coco.
