I think that both Josie and BB have sold her well. They present her as down-to-earth, which is what she tells people. They highlight her funny moments, and she says she "realizes" she is funny. They focus on John James' issues, and she says that he has two sides, is frustrating, is very strange, etc. You also have a lot of the HMs praising her constantly (for what -- I'm not quite sure). It's like a joint effort between Josie, BB, and virtually all of the remaining HMs (not the evicted ones -- but they have less say and less influence). Tell people something enough and they believe it.

Plus a regular TV viewer might completely miss out on the fact that she spends most of her time in bed, that she completely made up all these nasty things that Caoimhe supposedly did, that she played a lot of manipulative games with John James, etc.
