Most Disliked:
Dexter 23.9%
Sallie 20.7%
Jemima 18.5%

There's a pretty big drop off after that, with Callum at 12.0%. We'll see if this is representative of the larger viewing audience.

Most Liked:
Sallie 28.4% (most supporters of all housemates)
Dexter 11.5%
Jemima 1.4% (fewest supporters of all housemates)

It looks like Jemima (as of launch night 2), has a significant number of detractors, and no audience support to speak of. If it's a vote to save, she's probably a goner. Callum could have a similar problem (dislike: 12.0%, like: 2.9%).
